Microsoft Windows Hidden Malicious Software Removal Tool

The Microsoft Windows Malicious Software Removal Tool helps remove specific, prevalent malicious software from computers that are running Windows 7, Windows Vista, Windows Server 2003, Windows Server 2008, or Windows XP. 

The Microsoft Malicious Software Removal Tool does not replace an antivirus product. It is strictly a post-infection removal tool. Therefore, I strongly recommend that you install and use an up-to-date antivirus product.

The Microsoft Malicious Software Removal Tool differs from an antivirus product in three key ways:

• The tool removes malicious software from an already-infected computer. Antivirus products block malicious software from running on a computer. It is significantly more desirable to block malicious software from running on a computer than to remove it after infection.
• The tool removes only specific prevalent malicious software. Specific prevalent malicious software is a small subset of all the malicious software that exists today.

• The tool focuses on the detection and removal of active malicious software. Active malicious software is malicious software that is currently running on the computer. The tool cannot remove malicious software that is not running. However, an antivirus product can perform this task. 

 To open this tool: 

1. Go to  Start >>Run.
2. Type CMD.
3. Now type MRT in the Command Prompt and hit Enter.
