Herb:
Uninstalling and reinstalling AVG won't solve the problem. This problem with the update manager occurs occasionally since AVG was upgraded from 7.5 to 8.0.
When it does, go
here to download the latest definition file. Ignore the "editor's note". Save the downloaded file somewhere - preferably in a folder on your desktop or on the desktop where it's easy to find.
Right-click the AVG taskbar icon and then click "Open AVG User Interface".
When the AVG window appears, click Tools - Update From Directory.
When the "Browse For Folder" window appears, browse to the location you saved the file and then click OK.
After the definition update has been installed, you can deleted the saved downloaded file.
