If you know anyone who is going to college you might be able to get the Corporate version of Symantec AntiVirus. I still have mine from when I was in school. I love it, unobtrusive and takes up very little memory.
Thanks, Hype, but the Nod 32 failed me. I had it installed, and it couldn't detect a virus. I installed AVG and it cleaned my pc. I had a virused mail, which I opened, and besides, the NOD 32 could just delete the file. AVG disinfected it;)
