I have seen almost all internet securities and other antiviruses except MSE causing BSOD-s. Probably the latest version of that particular antivirus may run stable but I'm not sure because I never paid for antivirus. Me and my brother used AVG before but since 2008 when I was learning more about computers I permanently switched to MSE.
Registry cleaning, de-fragment, driver
update software can also be a cause. (defragment programs at a rare case) but surely would cause problems if the drivers
are not well suited with the system.
