Google Shows URL with Affiliate Ids

One affiliate is getting commission for Google traffic.

Since the last 2 days, G is displaying an affiliates id along my pages on it's SERPS:
www.example.com?AID=23755

That affiliate is earning commissions due to an error by Google. Is there anything I can do?

general opinion was that G dicounts PR gain from affiliate links, AND, filters out affiliate links from SERPS

what I meant here is that Google attempts to filter out affiliate links atleast as far as PR benefit goes. Thus it has filters for words like AID, AIFF, etc.
