Windows’s Malicious Software Removal Tool (MSRT) is ok, but it’s not great. On the plus side, it’s free, and it can detect and remove prevalent malicious software like Blaster, Sasser, and Mydoom. It’s designed to run in the background during Windows updates, and it targets specific well-known malware families. Although it doesn’t provide real-time protection or comprehensive scanning options, it can be useful in situations where you suspect you have a particular threat.
However, relying solely on MSRT is inadequate for complete protection. It should be used in conjunction with a dedicated antivirus or anti-malware app that provides real-time scanning, broader threat detection, and other advanced security features.
