No Outlook. No IIS.
But if you still want a signature scanner... I used to recommend Dr Solomon's and Vet from Cybec, but McAfee - whom I don't particularly trust - bought the former and Network Associates bought the latter.
I also recall a clever little product called Victor Charlie. I wonder what happened to it. It was really a file integrity manager, but it had it all packaged up so well and had a nifty signature scanner for the "common" ones that it could self update from "suspicious" files.
