Wormblaster is a freeware anti-virus for Windows operating systems. It can scan for and remove different threats such as viruses, and Trojan horses. Program is small/compact and easy to use.
The interface of the program isn't that good. But it has a virus database that catches most viruses. But as with most anti-virus tools, this too has a problem of false detections( catching files that aren't actually viruses).
It is worth trying if you had bad experiences with paid anti-virus softwares.
