A new type of Trojan has emerged that appears very territorial about what other malware it shares your computer with. Dubbed SpamThru, one of the first things this Trojan does when it sneaks on to your computer is to install a real and functioning copy of Kaspersky Labs' anti-virus software. The goal is to search for and remove any other viruses or Troajns that may already be on your computer and competing for space.

I guess it takes one to know one, but not the best way to do a virus scan. So far SpamThru focuses on turning infected computers into spam engines that will combine with other infected computers to send millions of spam emails. Safe to assume that identity theft is not far behind.

Maybe you should do a thorough virus scan, before someone else does.
