How to remove VirusBlast
What this program does: VirusBlast is a rogue anti-spyware application that gets installed along with malware without asking for permission or that is suggested by sites that are of dubious nature. This program can also be accompanied by other malware that changes your desktop background to a fake warning or by Trojans that issue fake taskbar security alerts. These are all used as a scare tactic to have you purchase their commercial software. A screenshot of this program can be seen below.
