Make sure you can see hidden folders and file extensions. Go to the Program Files\AVG\AVG9 folder. Alter the names of these files by adding something like.bak after each one (example: avgfree_us.bak)
DISCLAIMER: This tweak worked for me on AVG9 FREE version, I don't know if it will work on the full version.
