hmm... free anti-virus? my grandpa was telling about something that's free and some of his fellow computer geeks recommend, i think it's called
Grisoft... i've never tried it, though. i've got my school's free symantec anti-virus, and that works great (at least it has for me... i know others that haven't been so fortunate). i dunno if symantec has any free stuff, though. i believe norton is another good av company.
