Help. Frost Atronach following me!

[aufisch]

I recently installed Oblivion again. This time the Steam Version (GOTY). This is the third time that I am playing through Oblivion but I have never chosen the Sign of the Atronach before.

My problem is: the first time I fast-travel, a Frost-Atronach appears and keeps following me from then on I really don't want that!

I checked my inventory and I don't even have the "summon frost atronach" spell yet.
I also have of course frostcrag and all the other DLC's installed (including the unofficial Patches), but I haven't even been up there in this new game!

Does anyone know where this frost-atronach comes from, and how to get rid of it?

I do have the Akaviri-War dog as a follower installed, but do not run any other follower mods. All my other mods are either Environmental (All Natural, Immersive Interior, Tree overhaul, Grass.....), UI (DarniFied, Dynamic Map...). Plus AFK-Weye, and the Leveler's Cheat.

No it is not hostile. It seems to be a (unwanted) follower and I don't seem to be able to kill it either.

Ok I really have a problem. I used the console to disable to frost atronach (I was not able to dismiss it), and the next time I fast-travelled I "get" a storm atronach AND and flame atronach. What is going on here?

[aufisch]

Disabling the mods didn't remove the atronachs. However, I now suspect that it was my bashed patch that was the culprit. I re-built the patch omitting anything but All-Natural and its requirements, and I haven't received any new atronachs (I killed the other two using the console) whenever I fast-travel. Yay!! :)
