Interactive Brands / quad-cleaner
Quad-Cleaner is actually a "Rogue" software. Rogue programs inform you to have problems in your computer, which don't even actually exists. They are made to scam money. When the software is bought, they will either do nothing (Actually, the software does nothing), or they will make the software pretend to do something about these "virtual non-existant problems". Sorry, but you have been scammed. :/
I found an ad on Kongregate.com too about this one. I used a Firefox Add-on called WOT (Also known as MyWOT or Web of Trust) to check it's reputation, and bingo. It was showing orange light, which means bad reputation. It's really helpful. You should also get it already if you don't have one.
PS: I found this complaint with Google. The ad on Kongregate was actually from Google, so Google failed. :D
