Can Norton security expiring make youtube stop working?

[alucardx]

I've been fixing computers for a few years now and I can confirm when programs like Norton and MacAfee expire or are not activated then can start blocking some Internet access. The only way to be sure if this is your problem is to uninstall Norton and reinstall another anti virus program.

My choice is Avira - http://www.avira.com/en/avira-free-antivirus

or just do an internet search for others. Otherwise try clearing out your temp internet files - http://www.wikihow.com/Clear-Your-Browser's-Cache

Sometimes that helps.
