I have auto update enabled and after a restart my Windows screen started flickering and became unusable. Event log contained this error:

Task manager showed thumbnail handler extraction host task multiple times and the number of it continously increasing. I was able to make a crash dump and analyzed with windbg. It showed bushell.dll as the crashing module. It happened 10/07/2014 after the n360 update and restart with the version 21.4.0.13. I needed to recover to an earlier system restore point w/ earlier n360 build. It solved the issue.
Symantec engineers please take a look on the dump I attached and release a fix please.
