I installed the Norton 360 upgrade about 2 weeks ago, and since then I have had periodic internet connectivity problems on 1 of my 2 PCs running the new version. About once a day, I get disconnected from the network and am forced to reboot. It seems to occur after periods of inactivity. The PC having issues is running Win7 SP1 with IE11. I am also having issues with the screen resolution changing. Running a full system scan and rebooting resolves the issue. The other PC is older, running XP, and has not encountered either of issues.
