Don't fret about it. It seems we must have a few dozen posts like this.
For the last couple of years I have been using AVG which is a free anti-virus program from Grisoft. I received a notice last week that their free version was being discontinued as of January 15, 2007. Can anyone recommend another free anti-virus program? I don't mind paying for a retail program but I stopped using Norton because I feel that you should only have to pay once for the program and not every year! Thanks to anyone that can recommend some free programs.
