I have 2 PC's running Windows 7 and Norton Internet Security 22.5.2.15. Everything was fine until yesterday on both machines until yesterday. Latest Windows secrity patch installed and, unusually, on restart norton ran a perfomance fix on both machines. The windows action centre then reported firewall and virus protection off messages despite Norton saying "protected". This problem was fixed by perfoming a reboot and messages have disappeared from Action Centre on both pc's. Unfortunately, both pc's now exhibiting another proble. Every evening on both pc's we run a scan (sometime quick, sometimes full) and choose the turn off computer option for when scan completed. On completion of scans, the computers do not shut down and Norton screen still showing, after completing scan.
A fix for this frustrating problem (avoiding re-installation) would be gratefully appreciated.
Many thanks in advance.
