It seems to be fixed now on one computer, but not my other. Both are Windows 8 Pro with Media Center Pack systems.
Running Windows 8 Pro, Google Chrome, and IE10.
It's not working on one computer here in Chrome, but works fine in IE10 this computer, works fine on two other networked computers. (in IE10 and Chrome)
I have disabled and removed the Avast WebRep from Chrome, added it back in, run a repair install on Avast, restored my Chrome profile from a backup, uninstalled Chrome, Re-installed Chrome, and let it re-sync from my Google online profile to restore my Chrome settings.
Avast WebRep no longer works on this one computer in Chrome.
