F-Secures - Malware Scanner Easy Clean
Easy Clean is a small 4mb and fast tool. Very hady for both office admins and home users and is compatible with all recent 32-bit and 64-bit versions of the Microsoft Windows operating system.
The scan, including reboot, should not take more than a few minutes. The program can remove common viruses, worms and other types of malware that it detects on a system. The developers note however that it is not a full antivirus product, and as such can’t remove all malware from a system.
