Know How to Remove PowerShell.exe Virus [Hassles-Free Guide]

PowerShell is a ransomware-type virus that can enter an Operating System through a malicious file attached to a spam email message. The attachment is a ‘.js’ file that is known as a PowerShell script. 

When PowerShell enters your PC, it modifies and corrupts various data using encryption algorithms. Unlike other ransomware, PowerShell doesn’t rename or appends the extension to the encrypted name of a file. 

If your PC is infected by this ransomware, then an HTML file will be automatically placed on your desktop. The HTML file contains a message that will encourage you to visit a Tor website. If you mistakenly visit the recommended website, then you will be trapped by cybercriminals. 

If you have found an HTML file, then your PC seems to be affected by PowerShell. In such a situation, you must do something to remove the ransomware from your PC. Here, it has been clearly explained how to eliminate this malicious program from your PC. 

How Can PowerShell.exe Virus Affect your Computer?

Cybercriminals create emails and add malicious attachments to them. These malicious attachments might contain third-party software download sources, fake software updaters, and trojans. 

Unofficial software download sources present malicious executables as legitimate software. Thus, you trust the source and download the software on your PC. As a result, PowerShell enters your PC via the downloaded software and opens the door for cybercriminals. 

PowerShell affects the outdated Operating System installed on your PC and exploits it. Thus, you experience that your PC is suddenly running sluggishly and the applications aren’t responding. 

If the ransomware encrypts the Master Boot Record of a drive, then your PC won’t boot up in a live OS environment. Since the cybercriminals can access your files, they might steal your confidential information as well. 

Thus, it is necessary to take instant actions for making your PC ransomware free.
