After uprading to the latest antivirus version I receive an error while booting my system. My error is"S32EVNT1.dll and SYMEVENT.sys do not match". I am also running Norton System Works 2002 or 2004(can't recall at the moment). Updates were no longer available for that programs antivirus version and that's what promted the upgrade. Does any one know the cause and solution for this issue?
