hi, i don't know if this is the right forum but my norton protection centre just told me that my 'intrusion prevention' system is off. (don't know why 'cos i'd never turn owt off) i clicked on the red off word and 'turn on' and 'configure' came up. whether i try to configure it or click on turn on, nothing happens! the red off just stays and nothing changes. this is really getting me down and as my computer had frozen minutes before and security options wouldn't even come up (eg task manager) i'm worried that i may have a virus. could someone plz help or direct me to someone who can? thank you!
