Lost internet connection because of virus?

moments ago ive lost internet connection, so i cant do anything but play around with the norton internet security, i think it was a virus that caused it... @_@

anyway i clicked on "view history" and things appeared like this:

some ip's accessing my pc... that looks worrying, is that some sort of hackers?!?!?!

 

and theres some trojan.brisv.a detected yesterday, maybe that was it? my brother's been downloading crap from lime wire >=/ 

 

and ummm... im trying to system restore while the connection was gone, and it won't because of some error... T.T virus i presume?
