I use 360 Internet Security 2013 by Qihoo. It has 450+ million users worldwide.

I highly doubt that having 360 running alongside it (w/ real time detection off) impacted it, as a Web Developer I’m always online. I would have felt something a long time ago.

I believe that Avast 9 itself has been causing troubles. Potentially the Deep Screen technology. I tried installing Avast 8.1, but since I inserted my license it upgrade to version 9. Not happy about that :confused:

Prior to that, I had to clean install Windows 7, since Avast 9 screwed up my drivers (it damaged my keyboard drivers). Not happy about that. After running the awclear or whatever the program is called :confused:
