Doombot, a mix of of other bots and Mydoom

I received some reports of a few new massmailers spreading. This is detected either as a Mytob variant or as "Doombot". It mixes the code of Mydoom, Mytob and some IRCBots. Hopefully we will not see too much of these troublemakers ... I'm ready to go to Luxembourg for some interesting consultancy work. Even large corporates seems not always to apply their securiy policy quite well. So let's change this over there and help this company, like I always do.
