lots of chat on here of late about what virus protection and the like.
I've just had the fun of a new rebuild of my own pc cos i got a new sata drive (which for the record, sucks if you stick windows on it :x good ole ide again:oops:) and i've got backed up on a cd, avg, adaware, spybot, Win XP2 SP2 and zonealarm :p
but during install of avg was told of a new version and they're right lol
My advice would be download the new installer.
Disconnet from net.
Uninstall AVG 7.1 using the install, remove option
Connect to net and get updates.
I tried to do as they say, and add as a repair and it wouldn't work.
