The Repair didn’t work. I suspected it wouldn’t.

Can you also try the WinsockFix Utility for Windows 7 – http://windows7themes.net/winsock-fix-for-windows-7.html to see if this fixes your problem. Reboot after running this.

I believe Avast is working on it’s next update so you might want to see if this fixes your problem if the above does not fix it.
