More Dangerous Variant of MacDefender Malware Comes Up

Mac OS X users have been cautioned to be careful of a latest difference of the Mac Defender “scareware”.

MacGuard is extra dangerous than Mac Defender and some prior variations, consisting of Mac Protector and Mac Security as it does not need an administrator password to install, according to experts at security firm Intego.

The objective of the malware is the same — to influence victims to hand over their credit card details, even though the procedure is little dissimilar.  Partially, visiting an infected website repeatedly triggers the download of a file that installs itself on your Mac.

If you have the “Open safe files after downloading” alternative in Safari ensured the installation procedure will start routinely and the avRunner program will be installed on your Mac. This then downloads a second file package from a field belonging to the cybercriminals following the attack, while deleting the entire traces of the original installer files.

This second file is the MacGuard package, which will repeatedly install itself also.  It will after that command credit card features to relieve your Mac of the disease.


Intego proposes unchecking the Open safe files following downloading choice in Safari and if you must finish up on any website that appears like Mac OS X’s Finder window you must close the browser right away.  If the Installer opens, quit it straight away and check the Downloads foler for some unrecognized files and delete them.

Apple informed that an update to Mac OS S that would look and delete alternatives of the  Mac Defender malware on a Mac of the user, also caution them must they innocently attempt and download the file.
