Ultimate Fixer 2007 is a fake anti-spyware application made for removing bad parasites. It is called fake because Ultimate Fixer 2007 is usually installed silently through Trojans or through system security holes. As many other fake Anti-Spyware software Ultimate Fixer 2007 launches on Windows startup, runs silently and may generate popup windows saying that your computer is infected.
