I just bought a new computer today...of course they asked if they could sell me an antivirus program and I said no, I'll just download a free one!! He nearly crumpled to the floor!!! He said don't you know you get more viruses from those dang programs than you are protected from?? So I bought one. Guess I'd rather be protected for sure, since I'd already had a serious attack and had to go have it cleaned off the old machine!! Cost me way more than the software I bought!!
