Hello. I have a virus on my computer and I have used many programs to remove it like NAV, and Adaware SE and they can't get rid of it. It installs 3 files to my computer over and over. Here they are;

They do not do any damage to my PC that I have noticed. When I open Internet Explorer, this is my unchangable home page;

Is there any way to get rid of this? I can't understand what most of the virus says because it is in Italian or something. Thanks ahead of time
