Cannot update virus definitions in Avast Free version 5.0.677.0

Avast Free Antivirus / Premium Security
1

I had upgraded my version of Avast to 5.0.677.0 a few days ago, and I got a notification that the program was unable to update the virus definitions. On trying to manually upgrade, I got an error message “Cannot connect ot server”. I an using Windows Xp Home on a netbook, with Ashampoo firewall. I have given full access in Ashampoo to all the exec programs in the Avast folder in the Programs folder, including ashUpd.exe. I have reinstalled Avast, and get the same error. My update settings are that I am permanently connected to the internet, and I have tried both Direct Connection and Autodetect on the proxy settings.

Any help would be appreciated.

TIA.

Please try to delete the existing rules in Ashampoo and create them again from scratch.

Try deleting the avast! settings in the firewall so that when avast is trying to update the firewall will ask again

I remember Ashampoo Firewall has some compatibility problems with avast. :-

I suggest to uninstall Ashampoo Firewall, if avast can’t connect even after you delete existing rules.

I removed the Avast entries from Ashampoo, and tried to update Avast. Ashampoo informed me that Avast was trying to contact the internet when I opened Avast, and I set a rule allowing full access. However, when I tried to update Avast, I got no messages from Ashampoo, and the update failed again. I turned off Ashampoo, and still no luck.

The problem seems to be restricted to this version 5 of Avast, as I had no problems with 4.8—in fact I have 4.8 running just fine on another machine with Ashampoo.

Any suggestions?

Hello;

I can confirm that a compleet uninstall the ashampoo fire wall free will help. I just did it.
After the uninstal in the windows xp save mode all the update possibilities are working allright.

Now i have to find a good en free firewall which will work good with avast antivirus.

We had several threads here on the forum that Asyn and I were involved in regarding Ashampoo FW causing problems with Avast. Once this FW was uninstalled, Avast worked fine for ALL the users.
