SpySheriff is a corrupt illegally distributed anti-spyware program. It is secretly installed to victim computers by various trojans and through certain web browser exploits. Once executed, SpySheriff registers itself in the system and runs a payload. It changes the desktop background to a fake warning message, forbids access to some web sites and may even block any attempts to connect to the Internet. The parasite can also disable some Windows essential components and tools such as the System Restore and the Date and Time application. In some cases SpySheriff may attempt to delete certain installed anti-spyware programs, crash the system and display bogus system error reports. This malware is able to prevent the user from uninstalling. It can also restore its removed components. SpySheriff automatically runs on every Windows startup.
Several installations ago I made the mistake of Downloading and Installing SpySheriff, it's website (www.spysheriff.com) does a convincing job of portraying it as a legitimate SpyWare Removal Program. However once I installed it my computer quickly became infected with all sorts of Adware and Spyware and through my best efforts I couldn't get rid of them. SpySheriff would go through its process and pretend to remove them while changing OS settings and locking up the internet. I eventually had to reformat my hard drive and re-install WindowsXP...I found out later that it was in fact SpySheriff that had caused the problem in the first place.
