Apple’s support team has reportedly been instructed by the company officials not to confirm or deny if a customer's Mac is infected with malware or not.

ZDNet's Ed Bott on Thursday published an internal document titled "About 'Mac Defender' Malware," which states that the trojan, which hit Macs in the disguise of a genuine security software for the OS X platform, is an issue in progress.

The documents states, "AppleCare does not provide support for removal of the malware. You should not confirm or deny whether the customer's Mac is infected or not."

Hundreds of Mac owners recently turned to Apple to get the fake security software, which goes by the name of both Mac Defender as well as Mac security, removed from their machines.

The fake security software embarrasses its victims by popping up pornographic pictures on the screen of the attacked machines.

Mac Defender presents with images which show an anti-virus scan taking place on their Macs. The images fallaciously claim that the machine is infected with serious malware and urge the users to download and install the anti-virus software. Once installed, the fake anti-virus software infects the machine.

AppleCare team is reportedly witnessing a 4 to 5-fold jump in the number of calls seeking support for getting rid of the malware.
