A fake security program for Apple computers called MACDefender has racked up a significant number of victims. Hundreds of people who installed the software have turned to Apple's forums for help to remove it. The program's tactic of peppering screens with pornographic pictures has made many keen to get rid of it. MACDefender seems to have been successful because of the work its creators did to make it appear high up in search results. The number of people seeking help was uncovered by ZDNet journalist Ed Bott. In a blog post, he wrote about finding more than 200 separate discussions on Apple's official forums about MACDefender. The volume of reports about the problem was "exceptional" in his experience, he said. A little dose of reality, I guess.
