Microsoft maintains an important tool for Windows users, the Malicious Software Removal Tool. If you have been using a Windows system (including Windows 7, Windows 10, and Windows 11) without antivirus software for some time, it is a good idea to use this tool to scan for malware that may be infecting your system. Rather, it is a spot-check tool when you know that your system was at risk of being infected with malware. Typically, anti-virus and anti-malware software such as Windows Defender, which runs automatically, blocks anything the Microsoft Windows Malicious Software Removal Tool finds.

So, if you have a good antivirus, you shouldn’t worry about running this tool. Never rely solely on running the Malicious Software Removal Tool regularly to protect your system. You should always have an antivirus tool installed and running in the background. There are even free antivirus tools that will effectively protect your system, such as Malwarebytes. You should also make sure that Windows Firewall and Windows Defender are enabled.
