I stand corrected. However, I decided to go for the whole package (which is not free) not just anti virus. Right now I'm using the free trial so I have time to decide if I want to go all out or take the chance on just virus patrol. I have two teenagers using this machine for all sorts of things beyond homework. On my old pc I used free AVG, spybotS&D, Ad-aware SE, hijack this and something else. The combination worked well enough for windows98 with dial-up. Now, I think I might need a little more protection what with music downloads, IM, youtube and goodness knows what else goes on when I'm not looking.
