trojan.gen.2 keeps coming back

So yesterday I somehow got the trojan.gen.2 virus and it keeps attacking me every 4 mins or so by that and a trojan horse. Norton 360 keeps blocking and quarantining but it keeps coming back.


I've done a full system scan and used Norton Eraser tool and it hasn't solved the problem!
Please please help!

 

The trojan.gen.2 keeps creating the following: c:\windows\installer\{cea0a3ad-2ed8-03e7-6196-0fd2a981fd4e}\u\80000000.@

 

PS. If this should have been posted in the Norton 360 forum, I could always restart it there.
