Trojans?

My virus scanner says there is a trojan in the advertisements. Is this true or is it just paranoid?

I got the same warning (blocked trojan. The message was to short. Can’t say which one).
(I think it was from some “western game advertisement”)

I have reactivated my ABP for blenderartists.

I keep my Trojan’s in my wallet, that way they do not effect my virus scanner.
