Introduction to TypeScript remove item from an array.

In typescript, deleting or removing an element is defined as extracting an element of the specified index of an array and replacing that element with a new element or completely deleting that item from the array is known as removing an item in the array. Therefore, removing an element in the array is a process of removing or deleting any item from the given array with the help of methods provided by typescript arrays such as pop(), shift(), and splice() functions & delete operator are used for removing the item in array but delete() function is only used when we want to remove the property from array object with its hole left in the array which cannot be shifted as index or keys don’t shift id delete() function is used. So it is recommended not to use the delete operator.

In typescript, to remove an element in the array, we use different functions, and each has a different syntax.


This is the array function used for updating the array by adding or removing elements using the splice() function with the given arguments whether to remove or add the elements t the array according to the arguments passed to this function.

arr1.splice( index_num, no_of_ele, [ele_to_add1],[….., n]);


index_num: This parameter specifies the index number from where to start altering or updating an array.

num_of_ele: This parameter specifies the number in integer format of how many numbers of elements after the particular index specified must be removed.

Ele_to_add: This parameter specifies the set of elements to be added to the array after removing the old elements from the array.

This splice() function returns the updated array after removing and adding the elements to the array according to the arguments specified.


Syntax: arr2.shift()

This array function is used to remove an element in the array where this function has no parameter as it always removes the first element of the given array. It also returns the same removed element, which is a single element returned.


Syntax: arr3.pop()

This is also an array function used for removing the element in the array and works exactly opposite to the shift() function. This function also has no parameters as it always removes the last element from the given array, where this element itself is returned as the return value of this function.

How to remove an element or item from the array in typescript?


In the below example, we will demonstrate the splice() function for removing the element in the array.

console.log(" Demonstration of removing element in the array using splice() function") var course_arr1 = ["Perl", "Java", "Python", "Fortan", "Ruby", "Unix"]; console.log(" The given array is as follows: ") console.log(course_arr1) var ele_rem1 = course_arr1.splice(4, 1); console.log(" The removed element from the given array is: " + ele_rem1); console.log(" The updated array after removing one element is:") console.log(course_arr1)


In the above program, we first declare an array with elements and its value as “course_arr1”, which consists of 6 elements, and indexing starts from 0. Therefore, when the splice() function is applied to this array having passed the parameters as (4,1), which indicates to remove the element from index 4 and remove only 1 element. Thus this results in the updated array where the element at the 4th index is removed, and the new array consists of only 5 elements, and the output of the above code can be seen in the above screenshot.


Now let us demonstrate the pop() function for removing an element from the end of the array.

console.log(" Demonstration of removing element in the array using pop() function") var course_arr1: number[] = [10, 20, 30, 40 ,50]; console.log(" The given array is as follows: ") console.log(course_arr1) var ele_rem1 = course_arr1.pop(); console.log(" The removed element from the given array is: " + ele_rem1); console.log(" The updated array after removing last element is:") console.log(course_arr1)

In the above program, we have declared an array of number type, which consists of 5 elements in the array. Then after applying the pop() function to the given array, it removes the last element by default as it will not take any arguments. Therefore, this function returns the removed element instead of an updated array, and therefore we are displaying the updated array after removing the element, which now consists of only 4 elements using console.log().


console.log(" Demonstration of removing element in the array using shift() function") var course_arr1: string[] = ["Google", "Educba", "Institute", "Delhi"]; console.log(" The given array is as follows: ") console.log(course_arr1) var ele_rem1 = course_arr1.shift(); console.log(" The removed element from the given array is: " + ele_rem1); console.log(" The updated array after removing first element is:") console.log(course_arr1)


In the above program, we declare an array that consists of 4 elements, and then we have applied the shift() function, which works exactly opposite to the pop() function as it removes the first element of the given array always as we do not pass any argument to this function where it results in the updated array with 3 elements which removes the first element. The output can be seen in the above screenshot.


In this article, we conclude that in typescript, we can remove an item in the array using 3 different array functions where; it is important to note that we use these functions according to their descriptions as given in the above article. In this, we also have recommended not to use the delete operator for removing, which doesn’t mean we cannot remove the element using this operator. Therefore we conclude that we use the functions and operators as per the requirements.

How To Use Associative Array In Typescript?

An object with one or more elements is known as an array. Each of these components can be an object or a simple data type. For example, you can put dates, strings, and numbers in the same array. Information can also be stored using associative arrays. An array that employs strings as indexes is known as an associative array.

You can create a mixed array that uses numeric and string indexes within a single array. The length of an array will only reflect the number of entries with numeric indexes if it has both numeric and string indexes. In terms of functionality, associative arrays and numeric arrays are similar. However, they differ in the words of their index. Each ID key in an associative array has a corresponding value.

In TypeScript, an associative array is an interface that lists keys with corresponding values. It can be used like a regular array, but the only difference is that it can be accessed using strings instead of numbers.

Syntax interface AssociativeArray { [key: string]: string } var associative_array: AssociativeArray[] = [] associative_array['key'] = 'value' console.log(associative_array['key'])

In the above syntax, we declare an associative array interface and an object of it, It looks the same as a normal array, but we use a string ‘key’ for the index and a value ‘value.’ We accessed the stored value by using our key.

Example 1

In the below example, we use the associative array to store a series of values with indexing as a string or key. We store name, language, roll, and phone number in the associative array and then retrieve the values from it. We displayed all the values in the console. We have declared an interface AssociativeArray to store the data type of the associative array.

interface AssociativeArray { [key: string]: string } var associative_array: AssociativeArray[] = [] associative_array['name'] = 'Tutorialspoint' associative_array['language'] = 'TypeScript' associative_array['roll'] = 12345 associative_array['phone'] = 9999999999 console.log('Name: ', associative_array['name']) console.log('Language: ', associative_array['language']) console.log('Roll: ', associative_array['roll']) console.log('Phone: ', associative_array['phone'])

On compiling, it will generate the following JavaScript code −

var associative_array = []; associative_array['name'] = 'Tutorialspoint'; associative_array['language'] = 'TypeScript'; associative_array['roll'] = 12345; associative_array['phone'] = 9999999999; console.log('Name: ', associative_array['name']); console.log('Language: ', associative_array['language']); console.log('Roll: ', associative_array['roll']); console.log('Phone: ', associative_array['phone']); Output

The above code will produce the following output −

Name: Tutorialspoint Language: TypeScript Roll: 12345 Phone: 9999999999

In the output, we showed all the stored values of the associated array.

Example 2

In the below example, we will see how to loop through the associative array. We are taking an associative array that stores the ‘hello’ word in different languages. Looping through the associative array is not like looping in a normal array because, in this case, we will get the keys of the associative array while using the ‘for in’ looping mechanism. We also need to use that key to get the actual stored values of the associative array. It is a very easy way to get all of the associative array’s values without manually getting them one by one. We have declared an interface AssociativeArray to store the data type of the associative array.

interface AssociativeArray { [key: string]: string } var hello_associated_array: AssociativeArray[] = [] hello_associated_array['english'] = 'Hello' hello_associated_array['spanish'] = 'hola' hello_associated_array['french'] = 'Bonjour' hello_associated_array['german'] = 'Guten tag' hello_associated_array['italian'] = 'salve' for (let key in hello_associated_array) { console.log(key + ': ' + hello_associated_array[key]) }

On compiling, it will generate the following JavaScript code −

var hello_associated_array = []; hello_associated_array['english'] = 'Hello'; hello_associated_array['spanish'] = 'hola'; hello_associated_array['french'] = 'Bonjour'; hello_associated_array['german'] = 'Guten tag'; hello_associated_array['italian'] = 'salve'; for (var key in hello_associated_array) { console.log(key + ': ' + hello_associated_array[key]); } Output

The above code will produce the following output −

english: Hello spanish: hola french: Bonjour german: Guten tag italian: salve

Just like we have used the ‘for in’ looping mechanism, we can also use the ‘forEach’ for looping through the associative array. The normal array’s properties and methods are available on the associative array, which is a very powerful tool.

Return An Array From A Udf

This post is going to look at how to return an array from a udf. My last post looked at how to return a range from a UDF and in that, I included a small, bonus function which gave you the interior color of a cell.

I’m going to modify that function so it becomes an array function, or an array formula as they are also known. Specifically it will become a multi-cell array function as it will return multiple values into multiple cells.

What is an Array?

An array is just a list of values, e.g. 1, 2, 3, 4, 5 is an array with 5 values, or elements

That was an example of a one dimensional array. Think of one dimension representing values along a straight line, like the x-axis on a chart.

A two dimensional array holds values that can be used to represent something that requires two things to identify it, e.g. the x and y co-ordinates on a chart, the squares on a chess board, or even the cells on your worksheet (A1, etc).

Three dimensional arrays contain three lists of values used to identify something (the xyz co-ordinates) perhaps the latitude, longitude and height above sea level of a point on the Earth’s surface.

You can have more dimensions of course if you need them, but for my example we’re sticking with just one.

Returning Arrays of Different Sizes

In order to process an unknown number of values, we need to work out how many values are passed into our function and then allocate the appropriate amount of storage in an array.

Initially we allocate an unknown amount of storage space for the array named Result():

Dim Result() As Variant

Once the function is called we can work out how many cells are in the range we’re passing into the function. We can do this by using Application.Caller which gives us a Range object, as long as our function is called from a cell. This range is the range of cells passed into the function.

We can work out how many cells in the range and whether we’re passing a row or a column into the function

With Application.Caller CallerRows = .Rows.Count CallerCols = .Columns.Count End With

The number of cells in the range is CallerRows * CallerCols, so we redimension the array to hold a value for each of those cells.

'ReDimension the array to fit all the elements (cells) ReDim Result(1 To CallerRows * CallerCols)

If we pass in a range containing 6 cells, then our result will contain 6 values. Remember that this function is only dealing with one dimensional arrays, that is, values either in a row or a column.

If we pass in a range containing 10 cells, but allocate less than 10 cells for the result, we’ll get #VALUE! errors.

If we pass in 6 cells, and allocate more than 6 cells for the result, cells 7 onwards will be filled with 0.

How you choose to deal with this is up to. You can write your own error handling, or just let Excel deal with it.

Don’t Forget

This is an array formula, so when you enter it you must use CTRL+SHIFT+ENTER. That is, hold down CTRL and SHIFT, then press ENTER.

Fixed Sized Arrays

If you know the number of elements in your array will be fixed you can specify this and not worry about working it out when the function is called, For example, here’s a 10 element array:

Dim myResult(1 To 10) As Variant

But passing in a range with more or less than 10 elements could easily break your function.

Array Orientation

By default a function will return an array as a row. If you want the results to go into a column, you need to transpose the array

'Transpose the result if returning to a column GetColor = Application.Transpose(Result) Else GetColor = Result End If

Python: Remove Punctuation From String, 4 Ways

One common task when working with text data in Python is removing punctuation marks from strings. Punctuation marks can be a nuisance when performing text analysis or natural language processing tasks, and removing them lets you clean up your data and focus on more important aspects, such as word frequency and sentiment analysis.

To remove punctuation from a string in Python, you can use the str.translate() method with the .maketrans() method. You can also use a “for” loop to construct a new string excluding punctuation marks.

In this guide, we’ll explore different methods and techniques to remove punctuation marks from strings in Python. This will help you choose the most suitable method for your project.

Let’s get into it!

Before we start writing the code for removing punctuation characters from a string, let’s quickly review some of the basic concepts of removing punctuation from a string in Python.

In Python, strings are sequences of characters enclosed in either single or double quotes. These characters can include letters, digits, special characters, or special symbols, such as punctuation marks.

You can use built-in functions and methods specifically designed for Python string manipulation to manipulate strings and perform substitutions to remove that random errant question mark.

Punctuation marks are symbols used in written language to clarify sentence structure. These marks include commas, periods, exclamation marks, question marks, colons, semicolons, and more.

You may want to eliminate punctuation marks from a string for processing purposes, such as text analysis or natural language processing.

The following code is an example of removing punctuation from a string:

import string def remove_punctuation(input_string): # Make a translation table that maps all punctuation characters to None translator = str.maketrans("", "", string.punctuation) # Apply the translation table to the input string result = input_string.translate(translator) return result # Sample string with punctuation marks and spaces text = "Hello, world! This is a sample string with punctuation. And spaces!" # Remove punctuation from the string output = remove_punctuation(text) # Print the original and modified strings print("Original string:", text) print("String without punctuation:", output)

In the example above, the remove_punctuation() function takes an input string and creates a translation table using str.maketrans() that maps every punctuation character to None.

Then it applies the translation table to the input string using the translate() method. The result is a new string without any punctuation marks.

This method also preserves spaces between words, making it suitable for processing text data in various applications.

The output of the above code is:

Original string: Hello, world! This is a sample string with punctuation. And spaces! String without punctuation: Hello world This is a sample string with punctuation And spaces

We’ll now discuss different ways to remove punctuation from a string in Python.

Specifically, we’ll cover the following methods:

Using replace() method

Using translate() method

Using regular expressions

Using “for” loop

You can use the replace() method in Python to remove punctuation marks from a string. This method takes an initial pattern and a final pattern as parameters.

It returns a resultant string where characters of the initial pattern are replaced by characters in the final pattern.

By replacing each punctuation string with an empty string, we can effectively remove them from original string.

This example demonstrates using replace() method to remove punctuation from string:

s = "Hello, World!" s = s.replace(",", "") s = s.replace("!", "") print(s)

When you run this code, it’ll output:

Hello World

In this example, replace() removes the comma and the exclamation mark from the original string “Hello, World!”.

You can also use the translate() method to remove unwanted characters from a string in Python.

This method requires a translation table, which you can create using the maketrans() method. With the translation table set to strip punctuation marks, you can then use the translate() method to get the desired output.

This example shows you how to use the translate() method:

import string def remove_punctuation(input_string): # Make a translator object to replace punctuation with none translator = str.maketrans('', '', string.punctuation) # Use the translator return input_string.translate(translator) test_string = "Hello, World! It's a beautiful day." print(remove_punctuation(test_string))

In this script, we are using the str.maketrans() function to create a translation table, which maps each punctuation character into None. Then we use str.translate() function to apply this table to our string.

When you run this code, it’ll print:

Hello World Its a beautiful day

A regular expression pattern can be a powerful tool for text processing.

You can use the Python re module to create empty strings with a pattern that matches all punctuation marks. You can then use the sub() method to replace them with an empty string.

The following example demonstrates this method:

import re import string def remove_punctuation(input_string): # Make a regular expression that matches all punctuation # Use the regex return regex.sub('', input_string) test_string = "Hello, World! It's a beautiful day." print(remove_punctuation(test_string))

In this script, we’re compiling a regular expression that matches all punctuation. The re.escape(string.punctuation) part is needed because some punctuation string marks have special meaning in regular expression.

The sub() function then replaces any matched pattern string (in this case, any punctuation) with an empty string.

This will output:

Hello World Its a beautiful day

You can use a simple for loop to remove punctuation marks from a string. By iterating through each character in the input string and checking if it is a punctuation, you can build a new string that excludes all the punctuation marks.

The following example shows you how to use for loop to remove punctuation:

import string def remove_punctuation(input_string): # Make an empty string to hold the new string without punctuation no_punct = "" for char in input_string: # If the character is not punctuation, add it to the new string if char not in string.punctuation: no_punct += char return no_punct test_string = "Hello, World! It's a beautiful day." print(remove_punctuation(test_string))

In this script, we’re creating a new string no_punct and filling it with each character from the original string that’s not a punctuation mark.

When you run this code, it’ll output:

Hello World Its a beautiful day

So, all punctuation in the test_string has been removed.

To learn more about string manipulation in Python, check the following video:

Understanding how to manipulate and clean text data, such as removing punctuation from a string, is an essential skill when programming in Python. This is because text data is everywhere, in web pages, files, databases, and more. Therefore, knowing how to process and transform this data is invaluable.

Consider tasks like data analysis, machine learning, or even web development. Often, you’ll find yourself working with text. Punctuation can cause issues in these scenarios. It might skew your analysis or confuse your machine learning algorithm.

By learning how to remove unnecessary symbols, you’re equipping yourself with a powerful tool to prepare your data better. You make your text data cleaner, more uniform, and ready for further processing!

In this section, you’ll find some frequently asked questions you might have when removing punctuation from a string.

The “best” method depends on your specific situation and needs.

For simple, one-off replacements, str.replace() could be sufficient.

If you need to remove all punctuation, using str.translate() with str.maketrans(), or re.sub() with a regular expression, are more efficient.

A for loop can also be used for more control over the process.

Yes, context is key. In some natural language processing tasks, punctuation can provide valuable information about sentence structure or sentiment (like the difference between a statement and a question).

Yes, you can replace punctuation with any string you want, such as a space, using the techniques discussed in this article.

Yes, the re module works with any Unicode characters, so it can be used with text in any language.

However, the string.punctuation constant only includes punctuation commonly used in the English language.

You can customize all the methods mentioned to only remove specific punctuation marks.

For example, with str.replace(), you can specify the exact punctuation you want to replace. In the case of str.translate(), re.sub(), and the for loop method, you would adjust the punctuation list to include only the marks you want to remove.

How To Remove Malware From An Android Phone

One of Android’s greatest strengths is the open nature of the platform. Unlike iOS devices, you’re free to install any software you want. Unfortunately, that’s also a source of problems. 

Opening Android up to software outside of the official app store introduces the possibility of malware. If your Android phone has been afflicted by malware, you’ll want to remove it as soon as possible. In this article, you’ll learn how.

Table of Contents

Do I Have Malware?

We assume that since you’re reading this article, you suspect that your Android phone has a malware infection. However, malware is rarer than you might think. There are a few typical malware symptoms you’ll want to be aware of:

If that sounds like you, let’s move on to how you can deal with your malware issue.

Switch Off the Phone!

If you’re highly confident that your phone is infected with malware, switch it off completely. This should prevent the malware from “phoning home” and perhaps further infecting and taking control of your device. Remove the SIM card while you’re at it. 

When you’re ready to turn the phone on again, put it in Airplane Mode or switch off your WiFi router to prevent the device from connecting to the internet. Hopefully, you’ve cut off communications from the phone before any of your private data has been sent back to the malware authors. 

Use an Antivirus App

Using antivirus software is the most obvious thing to do when dealing with malware on an Android device, but some readers may not know that antivirus apps exist. Of course, it would be better to install an antivirus app before your phone is infected. 

That’s because some malware might interfere with the installation of antivirus applications. We’ll cover a few things you can do if it’s too late for an antivirus app. If installing an antivirus app is still viable for you, check out The Five Best Android Antivirus and Security Apps for verified and effective options.

Put Your Phone Into Safe Mode

Just like most desktop computers, Android offers a “Safe Mode.” In this mode, the phone doesn’t allow any third-party applications to run. It’s a good way to test whether it is in fact an app that’s causing your issues. If your phone’s problems disappear in Safe Mode, it’s likely malware.

To enter Safe Mode on Android 6 device and newer:

Press the power button.

From the options, tap and hold Power Off.

When you see Reboot to Safe Mode, select it and confirm.

Now, wait for your phone to restart. In Safe Mode, you can still remove apps, so this is a good opportunity to uninstall the apps you’re most suspicious of. If you’re lucky, that might remove the malware.

If you’re not that lucky, you’ll at least have stopped some of its functionality, allowing you to install a trusted antivirus app if necessary.

In Safe Mode, Remove App Admin Privileges

Safe Mode temporarily puts a stop to whatever third-party apps are doing on your phone. As mentioned above, you can use this as a chance to delete suspicious apps. However, you should also take the opportunity to review which applications are listed as “Device Administrators.” Apps with this level of privilege can do extreme things, such as erasing the entire phone.

Some applications need administrator privileges to do their job, but such apps have explicit justifications listed in the Device Administrators list.

On our Samsung S21 Ultra unit, the menu is called “Device admin apps” and is listed under “Other security settings” within the Biometrics and security menu. Few apps should have this privilege toggled on, and you should disable this permission for any applications you don’t know for sure should have complete control of your phone.

Factory Reset Your Phone

Yes, completely wiping and resetting your phone to its out-of-the-box state may feel a little drastic. However, it could be the fastest way to remove malware from an Android phone. 

It should be no more than a mild inconvenience for most people since all your information is in the cloud. So, once you’ve signed in with your Google account after the reset, your data should be restored automatically. Before you reset, read Google’s backup and restore document, so you’re sure how it works.

Serious Infections Such As Rootkits

Certain types of malware prove harder to remove from your Android phone than your typical bug. Some of them are so tough that they’ll survive a factory reset! Rootkits are a prime example of such a hard-to-kill malicious program.

A rootkit is a type of malware that installs itself into the core parts of the operating system. Normally, those critical parts of the software running your phone would be completely off-limits, but hackers find exploits in systems all the time and use those to enable the installation of rootkits.

Rootkit Security Warning on Red Binary Technology Background

Rootkits are almost impossible to detect, but poorly-written ones can still produce classic malware symptoms. They are the most dangerous form of malware because they offer complete control of your phone to a stranger. They can spy on you and do with your phone data what they like.

Antivirus makers aren’t sitting on their hands. Apps like Avast Antivirus also come with a built-in rootkit scanner. Of course, it’s not clear how effective they are because we can’t know about the rootkits these scanners miss, but it’s better than nothing!

An Ounce of Prevention

Hopefully, if you were infected with malware, the above tips have helped cleanse your phone of evil. If it turns out you weren’t infected, that’s even better news!

Now we need to talk about not getting infected or victimized by malware in the first place:

Finding out you’ve got malware on your phone can feel like quite a violation, but with the right safeguards, you’ll almost certainly avoid becoming a victim in the first place.

How To Remove Search Marquis From Mac (2023)

Measure to be taken to block Search Marquis from entering Mac:

Always install apps from known or credible websites sites and applications.  

Only install extensions from the Chrome web store or trusted sources.

Search Marquis is a virus that affects the browser on your Mac.

It was a normal day when you opened your browser on Mac to surf the internet but noticed something unusual. Your browser is redirecting you to other search engines or web pages. Since you are pretty sure you haven’t made any changes or someone else, then the culprit will be the Search Marquis virus, also known as Search Baron!

So, what is the Search Marquis search engine virus, and how can you eliminate this browser search hijacker from your Mac? No worries, as I will provide information about this search Baron malware and guide you on removing Search Marquis from your Mac.

What is Search Marquis?

Its name might mislead you into believing it is a legitimate search engine, but Search Marquis is malicious software that aims to redirect users to unwanted websites and then extort money from them. In short, this Mac search engine virus torments users for the benefit of its creators.

Although Macs are generally less susceptible to malware and viruses, it is always good to know the most common Mac viruses and how to remove them. Search Marquis disguises itself as a useful browser extension to get access to your Mac and then changes the default search engine on Safari or other popular web browsers on Macs.

Apart from changing search engines, Search Marquis can also change the default start page browser preferences and settings or, even worse, send your user data to those unknown virus creators.

How do I know if my browser is affected by Search Marquis?

The first instance to know if the Search Baron virus has hijacked your browser is with the sudden change of Search Engine or start page on a browser.

If you try to change the browser settings back to how they used to be, it will soon revert to the way the virus wants it to be, making you realize that no matter what you do, it’s impossible to change browser settings. That’s your cue to eliminate Search Marquis on Safari or any other browsers on your Mac.

Users are mostly redirected to chúng tôi when the Search Marquis virus affects their Mac. But before reaching Bing, the virus will first lead users through some sketchy sites, mainly:

Reasons why Mac gets affected by Search Marquis

Search Marquis primarily enters your Mac through a software packaging scheme called bundling. It comes with extensions or software that you may download from malicious or unknown sites. Ad affiliate networks bury the details about the bundled software in the accompanying terms and conditions. In turn, users unknowingly consent to the download and allow the affiliate networks to operate legally.

The best way to prevent this is by visiting trusted websites and paying attention to terms and conditions before installing anything on your device.

Now that we know about Search Marquis or how it gets into your Mac, let us now look at how to get rid of Search Marquis on your Mac. 

Trash malicious apps

You need to first find the malicious files and apps on your Mac that Search Marquis may hide. To do this, you need to open Activity Monitor.

Open Finder. 

Select Utilities.

Once opened, look for suspicious or unfamiliar resource-intensive activities in the CPU, Memory, and Battery tabs. Usually, these kinds of apps hide under an unthreatening name, so If you feel something seems questionable, simply search about it.

Once you find a suspicious app, select the suspicious app.

Note: You have to be careful when deleting files or processes. Deleting the wrong file may damage your system.

You can also stop apps from starting on the startup to prevent them from meddling with the browser settings or completely uninstall them.

Remove unwanted files

Apart from uninstalling all the suspicious apps, you need to ensure deleting all the files of the respective apps. Not only will this help you block Search Marquis from Safari or any other browsers on your Mac, but it will also help you free up space on your Mac.

Open Finder.

Hit Go option from the menu bar → select Go to Folder.

Next, copy-paste these commands in the search dialog box one at a time → press return:

~/Library/Application Support: The Application Support folder is the place where apps store the files to operate. Here, check for recently generated suspicious folders, specifically the ones unrelated to Apple apps and products you don’t remember installing. Some commonly known malicious folder names including: IdeaShared, ProgressSite, and UtilityParze.

/Library/LaunchDaemons: Launch Daemons is an internal service for running macOS. Sometimes, the Mac search virus files can be found in this directory, and hence you need to also check out files here. Some examples: com.ExpertModuleSearchDaemon.plist, com.applauncher.plist, and com.startup.plist.

com.Search Marquis

com.Search Marquis.plist





Note: Sometimes, Search Marquis files will stay hidden, so you might have to unhide these files and folders to find and delete those uninvited guests. Remember, it is hard to distinguish what is important and what is not. Hence, before deleting them, do a quick search on the internet and then decide.

Check and remove suspicious login items

In business and company settings, IT admins use profiles to control the behavior of their employees’ devices. These profiles may restrict specific actions and configure their Macs to do different things.

Similarly, browser hijackers and adware may use configuration profiles to prevent users from removing malicious programs from their devices, including changing their browser settings. Some examples of profile configurations include: TechSignalSearch, AdminPrefs, Chrome Settings, and MainSearchPlatform. To remove login items, do the following:

On macOS Ventura or later:

Open System Settings.

Choose General.

Go to System Preferences → Users & Groups.

Check for any suspicious apps → hit the minus (-) button.

Choose Remove.

Apart from that, you need to check and delete any unknown profiles on your Mac as Search Marquis virus might create a custom profile to restrict specific actions to prevent users from removing Search marquis on Mac and make browser settings.
