Hi,
I'm having a similar problem- however, as a home user, it looks like I've downloaded something not to my liking. :/
My MAS states that I have an update of Lion waiting... but I've never purchased Lion. I've purchased a total of 10 apps from the MAS, from what I can see they're all legitimate. When searching my HD for rogue _MASReceipt folders, all that come up (even on a root search using FAF) are the correct 10 apps.
When I go into the MAS and pull up each app, it is showing as being installed (so, I don't have one app spoofing itself as Lion this way).
A google of the foreign Apple ID gives no hits.
A text search of every file in my Application folder gives no hits on this Apple ID.
The receipt file inside of _MASReceipt is encrypted- there are no Apple IDs in plain text form. So, examination of this file yields nothing as well.
How do I identify the pirated app so that I can get rid of it?!? I would like to actually upgrade to Lion; and I'm prevented due to this thing.
Thanks.
