^^yep,some viruses don't do anthing but make copies of themselves,i mean like thousands of copies,bloody lame viruses.Only option left is either to disinfect every file which often results in 'critical dll missing' or just reinstall.
even I didn't used to care about viruses,virus aaya just do a reinstall but lately reinstalling windows seems a waste of time!My zune is lying around with just a handful of songs in absence of windows.I am getting a 8600gt within 4-5 days so I guess I will have to install windows soon enough.
Anyways Isn't avast free edition good enough?A firewall is a must in windows,antivirus is just optional.
