I installed AVG Free edition on Friday, when I got my shiny new Vista laptop.
On Saturday, I had to visit a few sites, cos I 'misplaced' my Nero Premium 7 key. Then in the afternoon I decided, screw this, I'm sick and tired of AVG Free edition's notification bar that pops up - and bought AVG 8 Internet security. It comes to R420.
Well, tonight I decided to do a scan of the laptop and was horrified (but very happy in the end) to find numerous Trojan Horses and other stuff on my laptop. AVG Free edition never picked it up!!
I guess you get what you pay for....I feel safe on the internet now.
