How do I delete Mumbo Jumbo. It will not allow me into my email or MSN

I bought a game disc at Walmart.  I enjoyed playing the games, but they were too long, and I couldn't keep playing.  I tried to get out and could not.  I shut down the computer.  When I tried to get to hotmail this morning, I could not.  Mumbo Jumbo has taken over and I cannot get to MSN or email.
The disc is called Variety Pack Luxor Adventures, Mahjong, and 5th Passage.
