Internet is fine but won't connect to any games?

Hi! My internet connection is totally fine and everything is fine on my laptop EXCEPT I can't connect (login) into ANY games (steam, league, minecraft, etc.)
Please help, I have norton security system, it says i have a virus or a treat and I ran a full system scan but nothing got fixed still got the warning
Thank you for answering! I really appreciate it! And yes I have restarted my laptop, uninstalled everything and re-installed them

Added (1). -like google chrome, skype, oovoo, etc all work fine

You might update Java and flash player.

Maybe it your firewall blocking the internet going in to games that you trying to play
if not try to disconnect your internet for 2 mins then connect again if not work try to restart your computer. If not work then i'm not sure what.

Sorry for the trouble. I'm Vineeth and I'm from the Norton Support team.

Can you please run a scan using the free Norton Power Eraser tool and see if it helps: http://www.Norton.com/npe?
