Xfire

For some reason Xfire. (xfire.com). Is being blocked everytime I start my
computor. How do I keep it from doing this?

 

Can you possibly explain the problem in greater details? What do you see?

 

Excuse me for my lack of detail.
When I boot up Vista I recieve a message "some applications have been
stopped from starting" in the bottom right, caused by windows defender (the
quote may be abit off). The pragram it is stopping xfire.exe. Xfire is a
widely used program. It is similar to MS Messenger Live but more oriantated
for games. As it allows for message while in a game and gives other game
information to others.
I am currently un-able to allow xfire to start on startup which is abit
annoying but not a major concern.
