Until now Mac users did not worry about viruses. Not that the OSX comes with a impenetrable anti-virus software but the virus programmers would not waste their time targeting 5% of the users. But the growing popularity and the cult status gained by Apple virus writers have turned their attention to the niche forcing the Cupertino company to issue a notice that Macs do need anti virus software. The note says: “Apple encourages the widespread use of multiple antivirus utilities so that virus programmers have more than one application to circumvent, thus making the whole virus writing process more difficult.” The note then goes on to mention three antivirus programs, with Intego VirusBarrier X5 listed first. This marks the end of recent “Get a Mac” ads, which publicly tried to ignore the threat of malware to Macs.
