“A new malware briefly flared in the Macworld this weekend but there’s only an extremely slim chance your Mac has been affected. Don’t panic at the inevitable hype: here’s how to protect yourself,” Jonny Evans writes for Computerworld.

MacDailyNews Take: Transmission users only:
Transmission’s website (https://www.transmissionbt.com) states:
Everyone running 2.90 on OS X should immediately upgrade to and run 2.92, as they may have downloaded a malware-infected file. This new version will make sure that the “OSX.KeRanger.A” ransomware (more information available here) is correctly removed from your computer.
Users of 2.91 should also immediately upgrade to and run 2.92. Even though 2.91 was never infected, it did not automatically remove the malware-infected file.
