Just to follow up on this, we looked into the Aureate issue in more detail. It turns out that the Cydoor installer is installing a directory called "AdCache" in the system32 folder. This is just a little cache to make the ads display more efficiently. Apparently, however, this is the same directory name that Aureate uses, and Ad-Aware incorrectly flags it as an Aureate file. It's really just a part of the Cydoor ads engine.
