Avast 4.7 updating error

Hi, this is my first visit to the forum and I need a little help/advice.

I have been running Avast as my AV for some time without any problems until lately. About a month ago I downloaded and installed Comodo Firewall to my PC and until now I have had no problems.

This last few days though I keep getting “Error, Avast was unable to update” messages. I assume it is something to do with Comodo and would appreciate any ideas in how to solve this problem.

I also have Spybot S&D, Adaware, SpywareBlaster and AVG Anti-spyware on my PC.

Basically, check (specially, in your case, number 3 below):

  1. If the servers.def file is corrupt or 0KB (C:\Program Files\Alwil Software\Avast4\Setup\servers.def).
    You can try and download the servers.def file, http://files.avast.com/iavs4x/servers.def and replace the one in the avast setup folder.

  2. If your subscription allows the update right now (i.e., if it is not expired).

  3. If your firewall settings and allow avast.setup to connect.
    If you’re not sure, just turn off your firewall (to be sure the update failure is not due to it).
    Maybe you should ‘remove’ avast.setup entry, try to update, receiving a new alert from the firewall, allowing it and checking it to remember.

  4. Check your proxy settings into avast!:
    Left click the avast icon > Settings
    Update (Basic) > Details > Proxy
    Make sure your browser is not set to “Work Offline” (this option is generally in the File menu).
    If it doesn’t help, try switching the proxy settings from “Auto-detect” to “No proxy” (I’m assuming you’re not connecting to the Internet via proxy).

Thanks for the reply Tech. I followed the insructions on pt4 and changed the proxy sttings to no proxy. I then saw that there was a test settings option which I clicked and this triggered the Comodo Allow/Deny feature which I allowed and checked the remember this command box so hopefully this will slove the problem.

I noticed when I was doing this that the update was set for every 240mins which I thought was a bit much and changed this to every 1440mins which I feel is more realistic.
