Norton blocking messenger devices

I’ve come to the conclusion that norton is blocking my access to messenger services like windows live messenger and skype. I’m able to log on to the messenger and start a chat, but everytime after about 1 minute I am kicked off the internet. My roommates also have these messengers and they work fine for them so I know it’s not a connection issue. I need help finding what I need to do to disbale a feature on norton or a way for norton to allow these messengers to work. Pllllllllllease help!
