When I try to shut down my computer get a message saying there is an error and this will shut down. I get this message repeatedly (6-8 times) and sometimes prevents computer from shuting down properly. Am seeing it is linked to my Nirton Antivirus from reading posts. (Very limited computer skill) Have 2006, and error started after I renewed this Dec. Anyone out there that can tell me how to make it stop or what I messed up? Thanks, loplady2003:confused:
