HELP! Can't open Norton Internet Security

Hi,

I really need help. I have windows 8 with 32 bit. Norton was working fine an hour ago but when Steam messenger started updating, I couldn't open my norton internet security anymore. I couldn't right click on it either. It's not doing anything, no error or pop ups.  I tried opening steam messenger but surprise surprise. It didn't work also. I'm pretty sure steam messenger had something to do with it but I just don't know what to do. I cant open norton nor right click on it.

What should I do?
