I've always been under the idea that UAC is really to keep people from accidentally deleting things in program files that they shouldn't be.  Or to keep folks without administrator privledges in a multi-user environment from doing the same.

I've always installed Poser outside of Program Files and have never had an issue with a virus hitting that folder... though I run a pretty tight ship here.  I also have UAC disabled (vista 64) and personally I also see it as a nanny ;)
