Can't download virus signatures

[Magnetoman]

I tried to download the new virus signatures today before scanning the computer manually. When I opened the download center and clicked on iVAS Update, it acted like it was going to work and then came up with an "Access Denied" popup box.

It had been working fine. Any suggestions?

Please, post the last 200-250 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log

Also check:

1) If your subscription allows the update right now (i.e., if it is not expired). Home (free) version need registering each 14 months.

2) 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.

3)  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 from "Auto-detect" to "No proxy" (I'm assuming you're not connecting to the Internet via proxy).
