Just a quick warning, I don't know if this is affecting other users but when I open TF2 Outpost and then leave it for a while it opens a scam "BT Survey" website- again this could just be me but there have been other reports of this scam happening on other's computers, but they didn't classify what site it was taking over.

If anyone else is having this problem just close the window, I'm asking someone on MalwareTips (who seem to be very good with this sort of thing) but I'm hoping its just an isolated case and no one else is being affected.
