Hi, I've been lurking here for a few months, but I'm posting this now because CyberDefender needs to be put on a Warning list!!! I recently installed CyberDefender
hxxp://www.cyberdefender.com/
and my computer immediately froze and shut down (the dreaded blue screen multiple times.) I finally got rid of it (it was almost impossible -- every time I tried to delete or uninstall it, the system froze.) I can't believe this company manages to exist!! AVOID CyberDefender!!! (Hopefully CCleaner and Revo managed to delete all the junk that CyberDefender installed. So far, so good.)
