I recently asked Norton 360 to scan a folder. After a while, I needed to do some work so clicked in "Stop Scan" and confirmed it. Norton appeared to continue to operate and could not be closed, nor could I access other Norton menus. I was eventually able to stop Norton by Restarting my PC. Has anyone else encountered this problem? I see some similar difficulties have been recorded for full scans and that Norton has been known to "hang" at 13% of scan performed, but I repeat, this happened when scanning a folder.
