Revo uninstaller is sort of a combined way to uninstall programs and clean up the registry for that programs left overs and some of the left over files/folders it might leave. It's not always 100% effective but its better than windows uninstall - which is really just running the programmers uninstaller. You can try to use revo... I always run it on its most aggressive scan. . To me it sounds like you might need to reinstall AVG 12 the older version..... disable it.... uninstall it maybe with Revo first... then follow up with the AVG uninstall tool .. most want you to run that tool from safe mode.

Found this note, regarding the error...which I hope I don't have some other kind of bad problem, as now i have no protection going. That "appcompat.txt" looks like it will be hard to manage! Oh me!!!

I would probably uninstall the new version followed by a reboot... then download and install the old version. Hopefully then you can uninstall the old cleanly before installing newest version. Here is a link that might be useful: http://www.oldapps.com/java.php

Start/search programs and files. Type msconfig. Run the program. Open the start up tab. Disable all start files related to Open Office. Return to Remove Programs and it should remove it.
