It's *highly* unlikely that you have a virus. Although there are some 
viruses for linux, in general, unless your a corporation running a 
server, you dont really need to worry about them at this point in time. 
Most Linux security threats are fixed within hours (alright, that might 
be a slight exaggeration), so as long as your updated, theres not much 
to worry about.

If the screen is freezing up, you either have a problem with your 
xorg.conf or something with your hardware is faulty.

What video card are you using?
