Yesterday, May 25, 2015, I replaced Norton Internet Security with Norton Security at the end of the former's subscription. The installation seemed to go without incident.
I tried yesterday to run a full system scan. After about 90 minutes it just stops. The scrolling of the file being scanned stops and the display just sits there.
I tried again today with the same results. Further, I cannot stop the scan or close the scanning window.
NIS would scan the system in about 2 hours and, when selected, put the computer to sleep when complete.
I am not sure where to look to fix this.
The computer is an Acer Aspire running Microsoft Windows 8.1.
Thanks.
