A Trojan software using a network called peer-to-peer to send directions to other computers with the same software on them. To team team up against other machines or to send out more spam. This software un-installs other Trojan and Spam software that you may have gotten on your machine. So it acts like a anti-virus software, but the only reason behind this is to get more processor usage for itself. I am sure that we may have more on this at a later time.
