AVG and Avast, i managed to get AVG down okay after a few probs In my opinion its very easy to use and to download, that Avast seemed a bit techy, plus he wouldn't let me on internet after i downloaded so i sacked it off. I think if you download AVG make sure you 'Unistall' whatever anti virus you have already including McAfee or whatever is already on machine when you bought it Its running fine and smooth
