Most of the "Lu" badged stuff is Symantec Live Update.
You are PROBABLY correct in thinking so.
I dumped them just after the new year so I can't test it, but have you tried a manual update and seen if ZoneAlarm goes off?
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
