Hi, The MS Windows Malicious Software Removal Tool available in 32-bit and 64-bit versions is not an anti-virus application but is intended to detect and remove specific malware such as, Blaster, Sasser and Mydoom. When anti-malware programs are designed for a specific task then the probability of success is much higher than generic programs. The tool removes malicious software from an already-infected computer. Again, this tool is not a replacement for an anti-virus product while Microsoft will be releasing an updated version every month. http://www.microsoft.com/download/en/details.aspx?id=16 What do you think of this program ? Is it a bad/good/excellent malware detection software? Thanks in advance !
