I have been using AVG 8 with no problems but had seen that Avast was recommended by quite a few people.
But it's slowing internet browsing down and when I've tried to upload images I've got a page load error message:
Connection Interrupted
The document contains no data.
The network link was interrupted while negotiating a connection. Please try again.
I'm not really sure If I've missed any obvious settings that I need to have ticked/unticked, left most things at defualt - I'm a total Anti-virus noob to be honest! Never had a virus that has caused me hassle and just got used to the simple settings in AVG
I've got Zonealarm running as well, in case that makes a difference.
