I have a PC running windows-XP-professional. It has been using the free AVG antivirus software without problems for many months. In the last few days the software was pestering me to upgrade to a new (still free) version which I decided to do today. But after performing the requested reboot, I get a window titled "AVG Installer - Error" with the text "A system restart is required in order to continue with the installation. Please restart your system and try again." There is a single "Ok" button on the window. If I then reboot, the exact same window will reappear every time.
Any ideas how I can break out of this endless loop?
EDIT: I should mention that while AVG was in the process of downloading and installing, I was, perhaps dangerously, downloading and installing a few other things - like updating to the latest firefox and adobe flash.
EDIT: If your answer involves downloading AVG again - then please advise what I should do about the existing half-baked AVG first, should I (could I) try and uninstall it first?
EDIT: Looking at the AVG forums, I see that other people have posted similar problems with version 11, but so far there are no replies to their questions :-(
EDIT: After looking around the forums some more I found this: http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=110317 ... that should fix it.
