if you have problems with "hung" updates in your avast! installations, please use this tool:http://public.avast.com/supp/FixUpdate.exe
For version 7.0.1407
please run FixUpdate.exe, then run VPS update from avast! GUI. You can ignore the question whether you want to run a program update after the repair is done, because there's no further program update available for 7.0.1407 at the moment.
For version 6.0.1367
please run FixUpdate.exe. After a few seconds, you will be asked whether you want to update the program (to version 7). If you choose to update, click "Yes" and wait several minutes for the process to be finished (you can check on the Maintenance / Update page - after the update is done, the page gets updated and says "Current version 7.0.1407", with a note that it's necessary to restart the machine to finish the update); then restart the computer.
The tool is meant to fix a specific problem, in particular the one mentioned e.g. here: http://forum.avast.com/index.php?topic=94454.0
If the machine is not affected by this particular problem, the tool will report so (usually with error code 2 or 11) and won't do anything.
If you did not experience any problems updating the virus definitions in the past 24 hours, just ignore this tool - there's no point in running it.
Again, we apologize for the inconvenience.
