I just posted this in response to Corina on the AmateurMasters Board:
"Corina,
Now that I see what is happening to the guy, it's not something either you or CCBill did, he already had the MoneyTree parasite in his system and browser! It can take over at random times, and it looked like it did when he was on the CCbill affiliate page.
What one of the varients does is randomly pop-up promos and ads for sites within the Moneytree system while someone is surfing. he blames it on the site he's on, without realizing that it's something already on his PC.
Tell him to scan his system with Ad-aware or similar program. he can also visit
http://www.doxdesk.com/parasite which will find it for him and give him the fix.
Danny"
