Hello NeilBlackley,
please follow the removal procedure according to this AVG Free Forum sticky post:

Are you using other protection application and firewall?
Thank you
I have tried to install AVG 2011 onto an ASUS running Vista that previously had AVG9,and it freezes about 70% of the way through. The computer completely freezes, the programme won't respond to cancel, and I can't turn the computer off. When I disconnect and reboot, I get an AVG prompt which goes into the same loop. When I try to uninstall AVG, the same thing happens. I am now left with no way of removing the programme, and no active anti-virus.
Any help desperately needed
