Cochise,
I will try to give you some guidance here. Firstly, the VRDB can take awhile especially the first time it runs. It needs to copy system files and depending on how extensive your files are, it may take from a few minutes to as long as 15-20.
The VRDB normally needs the system to be idle for about 5 minutes without any keystrokes for it to activate. If you did a "force" and it did not work, we have to look elsewhere for a solution.
Since you cannot manually update the db or program, then I would suspect a connection problem to the asw server.
Are you operating behind a firewall or proxy? Avast changes the server address to 127.0.01 so that it can scan emails. You may need to add the asw server addresses into the "pass" file of a firewall.
Some users of IE have found that they needed to add the asw servers to the "approved" internet zones.
If the VRDB icon is not rotating, then it usually means that it isn't working. You need to let the system idle for awhile, then watch the drive light on the computer. If it blinks continuosly for a bit, then the VRDB is running. If you right click on the A icon in the tray, and select About Avast, you should see the latest VPS (db) date.
Also, right clicking on the A icon and opening up Avast interface, the date of the last VRDB should show. If it does not indicate a date, then it has not run.
I know that this sounds pretty general at this point, but you did not give much to go on.
The AVAST server address can be found in one of the boards threads.
Also, Avast does not like other anti-virus software running with it. Avast must be the only av on the machine
Let me know what happens.
Have you tried a reinstall yet? I don't recommend it right off the bat, but I need to know if it has been tried.
Thanks
