Symantec Complaint - Bad everything - Norton 360
First of all I moved to Norton 360 and I could not get 2 out of 3 computers I licensed to update the program definitions. Customer support was useless. Re-install and if that don't work re-install again was the advice. It was possible to manual update so I did that. I eventually sorted out the problem myself. Norton 360 cannot pass though a proxy server and needs a live internet connection. So with the problem fixed I should be happy. The problem is with automatic updates installed 360 tries to update every few hours and when it does the computer becomes non-responsive until it finishes. A look at task manager reveals the problem which is multiple lucallbackproxy instances. One solution is a simple one .. switch off automatic updating.
The best solution would be to find yourself a product that actually helps not hinders you.
