Norton AVG = 0 Virus's
Free AVG = 17 Virus's
I am taking it, Free AVG is Grisoft AVG?
I have had it since day one, and more or less there day one of the release, i sware by it, it catches loads and loads, infact, i have not had a virus since i had it. And i download all the time, friends with norton have virus's every week.
I used norton with my laptop a few months back as it was free, i installed AVG after the trial and it showed up 17 virus;s that norton had missed for the 30days. Tut Tut norton, get it together...
