Why are my internet threds missing

[payo07]

I seem to be unable to install any program. Every time I insert my micro titanium antivirus plus i get an error screen.When i open google chrome or fire fox i get an "open with" screen. I am curious to know what kind of virus might cause this and how can i fix it?
