MS KB3000850
« on: November 19, 2014, 10:38:54 PM »
We've been able to duplicate this on two machines.

Windows 8.1 Pro
After installing Optional update KB3000850, the machines hang up - they cannot run network scripts, nor run many programs on the system.  Some work, but much doesn't.

You can't even restart or shutdown - it just hangs forever.

We noticed that on both systems, the Avast system tray icon never appeared.  So we thought to remove Avast.

If you get into MSCONFIG and force the system into safe mode - remove Avast using the Clear program - the system starts working perfectly.

Something about that KB messes up Avast.  Please make sure you avoid that KB for now until the Avast team has a chance to check it out.

Same issue here! We are using version 8.0.1603 (Endpoint protection plus) and after updating Windows yesterday we have several issues:

- PC unable to restart
- Internet Explorer does not start anymore
- Not able to debug in Visual Studio (issue with starting builds)

Please look at this ASAP!

EDIT
I've just uninstalled KB3000850 via the Control Panel (safe mode not even required) and after a reboot the system is back to normal. This seems like the preferred way since it does not require you to remove Avast (leaving your system unprotected).

We are having the exact same issues as well.  Lots of machines took that update.  It has not been very fun trying to go around and uninstall that update.  Hopefully this is resolved quickly.

Yup, just came here to mention this...  But already found that it is going to be addressed tomorrow morning.

https://forum.avast.com/index.php?topic=160717.msg1153446#msg1153446

We have been able to simulate the problem in our lab and I think we fixed this issue. This Windows updates calls new memory related functions which are not fully compatible with avast. We'll prepare EmUpdate with the patched driver tomorrow morning (it means, all & new avast installations should be patched immediately, that's how it works).

Edit:  And no need to remove avast as someone suggested, just remove the MS patch KB3000850 temporarily until avast can get patched.

No sign of the patch yet...  I got the impression that this would be a streaming update and/or something the mirror should pickup automatically...  Assuming your SOA server is healthy...

Looks like yet again the business product is lagging behind, hopefully someone from Avast can comment on when the patch will be available for the other versions of their software.

Is there a way to use SOA to remotely uninstall the Avast client?

So this hasn't been updated for the business product?  I have been following the other thread and seems like there is a patch for the personal side but I have not seen an update yet for the business side unless I have missed it?

As am I.  Avast team, can you confirm that the Business products will be getting the same fix coming soon?
