Microsoft Malicious Software Removal Tool

Microsoft's tool for removing malware from your computer. The program checks if your computer is infected with unwanted software (e.g. Blaster, Sasser, Mydoom viruses). If an infection is detected, the program will take care of the safe removal of these unwanted influences. In addition, the program is updated every second Tuesday of the month (automatic updates can be set), so you won't end up with an outdated version that can't remove some new parasites.
