I'd like to announce that it's possible to change the frequency of the advertising pop-ups (even completely disable in paid versions) in the recently updated version of AVG. Please visit this article (http://avgread.me/popups) to find out more.
removeavg.exe /norestart /skipask /silent /But the normal prompt still pops up
Alan, we didn't install AVG free in teh corporate environment, the previous IT guy did, we are trying to clean up his mess. And AVG support is less than helpfull with it.
FYI solved the issue myself. Posting it here for the next person, so they don't have to ask/ deal with AVG support for a simple answer
"C:\Program Files (x86)\AVG\AVG2012\avgmfapx.exe" /Appmode=Setup /uninstall /uilevel=Silent /dontrestart
