Help please!

--------------------------------------------------------------------------------

My laptop is crashing and running slow, i'm not massively tech savvy but have done all the checks I know. I have Norton 360 installed however it keeps disabling itself whenever I log off, can't get the auto protect to stay on and the fix button doesn't work. I've tried using a few other virus checkers but they won't complete a scan without the computer crashing. Any pointers what I can try?
