Avast 5: Cannot Update Virus Definitions

[cs1966]

I suggest an installation from the scratch:

1. Download the latest version of avast! Uninstall Utility and save it.
2. Download the latest avast! version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can't run it, try booting in Safe Mode and doing it from there. Anyway, boot after you've run it.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro.
7. Check and post the results.

Ok, did all this. Same thing - program version is up to date (5.0.462) but virus def's out of date (now I have 100309-0, current version is 100331-2). Cannot update.

Did you reboot after final installation?

ashupd.exe allowed in the firewall?

Same problem here...

When I try to update manually it tells me that the program and base are up to date but my versions are : 100228-0 (28feb2010) and 5.0.377

There a line telling me a new version is available (5.0.418) but won't download it !!!!

btw it's also written : Server unknown

[Zyndstoff (aka Steven Gail)]

5.0.377 is a beta.

download the free version from www.avast.com and install, let's see what happens then. Should be working thereafter.

ashupd.exe allowed in the firewall?

I don't see this listed among the applications in the firewall. But even turning the firewall off doesn't help.

Just reinstalled avast and it works now 100331-2 and 5.0.462

Thanks !!!

[Zyndstoff (aka Steven Gail)]

Well - at least one...

Okay, how about ...erhh... uninstall the firewall, reinstall avast, reinstall the firewall?

Maybe worth a try.

[Zyndstoff (aka Steven Gail)]

Okay, very nasty idea: search for ashupd.exe and start it by doubleclicking on it.
What happens?

Found it in the Alwil folder...absolutely nothing happens when you click on it. I've downloaded the program 3 times now after uninstalling the previous version. Each time it says I have the laatest prg version, but the virus def's change each time

What program version does it show? 5.0.462?

I'm running out of ideas, I must admit. I hope someone else with more ideas reads in the background and cuts in...

Well...although all of the help and suggestions provided by others here in the forums did not solve the problem I was having with Avast, everybody's efforts are much appreciated. However...for reasons unknown, Avast just finally auto-updated itself!
