What Is the Windows Powershell Virus?

The Windows PowerShell virus is a malicious script or program that uses Windows PowerShell to display and run unwanted pop-ups. The pop-ups come from different channels. Here are some of the most common possibilities:

  • 📍Downloading suspicious tools or software;
  • 📍Opening suspicious emails containing malicious files or attachments;
  • 📍Clicking on notifications on your web browser;
  • 📍Other suspicious activities or sources.

The Windows PowerShell virus can damage your system and your privacy. The longer you have it, the more consequences you can expect, including new malware, access to your microphone and sensitive data, changed settings, corrupted system files, poor device performance, etc. Therefore, it's imperative to learn how to recognize and remove a Windows Powershell virus.

How to Recognize a Windows Powershell Virus

powershell virus detection

Recognizing a Windows Powershell virus is easy if you know what to look for. However, if the purpose of the virus is to track your activity and steal data, you might have difficulty figuring out your device has been infected. Moreover, most antivirus systems even can't detect it on some occasions. So the bottom line is you must pay close attention to what's happening on your computer and your security.

Here are some signs you should look for when trying to determine if your computer has a Powershell virus:

  • 🚨Look for any unwanted ads or pop-ups when using your computer;
  • 🚨Check if your device is running slowly (including your internet connection). If your disk, CPU, or RAM memory usage is at its peak, you may have a virus;
  • 🚨New icons appear;
  • 🚨Your files or folders have been moved elsewhere or have been deleted;
  • 🚨You have suspicious processes running in your task manager;
  • 🚨You get unnecessary notifications or update requests for software you don't have or don't use;
  • 🚨You're getting occasional phishing forms in your notification center.

How to Remove the Windows Powershell Virus

You can use several methods to remove the Windows Powershell virus. Here are the exact steps for each you should follow.

Reset the Browser to Default Settings

Resetting your browser to default settings might help you "disable" the powershell.exe virus and remove any malicious plugins or tools operating within the browser. It can be a temporary solution that can help you mitigate further damage, but you should also use permanent solutions to remove the virus completely.

The process of resetting your browser to default settings depends on the browser you're using, but they're all similar. Since most Windows users use Google Chrome, let's take a look at the steps:

  1. Open Google Chrome.
  2. Click the three dots in the upper right corner and select Settings.

Use Antivirus or Anti-malware

One of the first methods you should try when you have a Windows Powershell virus is to use anti-malware or antivirus software. You can try a full scan by Windows Defender before using a third-party antivirus or malware removal tool.

Here are the steps:

  1. Click on Start and type Windows Security.
  2. Click on Windows Security.
    accessing windows security
  3. When the Windows Security window opens, click Virus & Threat Protection.

  4. Click on Scan options in the Current Threats section.

  5. Select Full Scan and click Scan Now.

  6. Wait until the process is completed (it might take several hours, depending on your device and storage).

If you still can't find the virus, you can resort to the third-party antivirus tools. The steps are similar: scan your device and then remove threats when they're found.

Use System Restore

If you're using the Windows System Restore feature and have a restore point available, you can use this option to restore your system to a point when you haven't had the virus. This option can work only if you've noticed the virus on time. Rolling back to a previous restore point might be ineffective if it's been there long.

Here's what you need to do:

  1. Click on Start and write System Restore.
  2. Click on Create a restore point.
    accessing create a restore point
  3. Click System Restore.
