A fake antivirus program which downloads itself onto your Mac, is a very rare virus specifically aimed at Apple’s computers.
The application is very well designed, and looks professional. There are a number of different screens, and the grammar and spelling are correct, the buttons are attractive, and the overall look and feel of the program give it a professional look. MAC Defender also opens web pages for pornographic web sites in the user’s web browser every few minutes. This is most likely to make users think that they are infected by a virus, and that paying for MAC Defender will relieve them of the problem. Having ‘scanned’ your computer MAC Defender will bring you to a register page where you can sign up for a 1-year, 2-year or lifetime license by entering your credit card details. Of course the software itself is completely useless and the virus results are bogus.
Apple has confirmed it has launched an investigation into the fake software and has issued its Apple Care team with instructions regarding what to do if a customer calls with the problem. An Apple Care representative has said that calls to the customer care centre were up by four to five times the normal volume and nearly all calls were dealing with MacDefender and its aliases.
In the past sites like these, which commonly deliver Windows malware, only delivered Windows .exe files.
