I have a serious problem with the Avast Emergency Update from 23.11.2013.
I've seen this process run twice on my system this week, and every time it has run, it has almost completely frozen my system. Almost all programs became unusable, all browsers freeze, skype freezes, I cannot shut down or restart, and cannot kill the 3614329593somemorenumbers.exe process, which also happens to be digitally signed by Avast Software. I used the reset button the first time, and today it happened again and I realized I can just disable avast self protection module and kill the process. The moment it is ended, everything is normal again.
Something is seriously wrong with this emergency update feature, as I didn't have this problem before updating to Avast 2014.9.0.2008. It cannot be uninstalled either from avast setup. I am using Vista 32 bit.
