For starters, I don't have Dawnguard and am on Xbox. Uthgerd attacks me when I hit stage 4 vampirism and try to talk to her. Do all followers do that? Are there any followers who don't care, or for that matter, evil followers in general? I don't really want to cure my vampirism and I'm not even ready to get DG. Especially with random vampire attacks. Any tips on how to effectively utilize a pre-Dawnguard vampire?

Kill that ugly hag and get an evil follower, i imagine people like Eola for example wont turn on you(not tested). plus shes hot. well except for that missing eye.

I think any of the followers with a 0 for their morality value shouldn't attack you when you are at stage 4. Haven't tested it though. Followers and their morality values are listed http://www.uesp.net/wiki/Skyrim:Followers.

I've had Dawnguard installed from the day it was released on xbox, so I can't say with any certainty but I think all followers will attack you at stage 4 regardless of their morality.

i read the title as 'uthgerd turned me on'....im ashamed

I know at least the followers you gain after completing the Dark Brotherhood questline won't attack you at stage 4 in vanilla Skyrim.
