The application called Win 7 Anti-Spyware 2011 decribed in this post is a virus and not some decent tool which you could trust. It belongs to the clan of many similar fake anti-viruses which change their name randomly depending on the operating system installed on the PC. Whatever the name is chosen, all such pests should not be trusted due to the fact that their only aim is to steal money from you. They are not able to deal with real infections.
