Hi,

I am following this thread with great interest, since I am experiencing the same issue. I noticed that it all started after I updated Avast! to version 6.0.1367.

Because I have other security programs running on my PC, I wanted to know if any of them was possibly interfering with Avast! Here is what I did, just in case this would help in the “investigation”…

  1. I shut down Comodo Firewall.
  2. I tried to update Avast! manually: it failed to update (the same way as before shutting down Comodo)
  3. I turned back on Comodo Firewall
  4. I shut down Webroot SecureAnywhere.
  5. I tried to update Avast! manually again: same result (update unsuccessful).
  6. Turned on Webroot SecureAnywhere, of course…

So, all that to say that I am not sure this issue is related to other security softwares…

p.s.: My OS is Windows 7 Pro x64 SP1
