A few times now i've had a few Trojen warnings from AVG while on interenet explorer. I've only jsut realised that it pops up when i'm on XBS. I have a homepage tab with XBS on it.
AVG has come up with Troajn Horse SHeur2.BYFE :c/users/user/appdata/local/temp/wsuydh.exe
I'm assuming its from an advert. I dont know which one it was when it popped up
