Another thing I find curious is that with all the various free antivirus software I have, not a one has ever detected a virus or worm–they all say my computer is clean. And, trust me, I never download a file if I don’t know what it is. I never even pass on “joke” emails from friends or any other kind of spam that friends ask you to send to your closest 100 friends. Never. So if none of the antivirus software I have ever says I am infected, am I infected?
