Norton mysteriously turned off and can't open IE

My laptop seems to have a huge blockage. I am guessing it is a virus. I have AntiVirus 2011 with Antiperspirant but all of a sudden it was turned off and I can't get it turn on. Should I try to upgrade to 2012 version? Obviously, I an not a techie. Help!

Have you tried rebooting?
