Please read the article.
A Mac with Windows malware is not affected. Just like a Windows machine with Apple malware is not affected.
These were files downloaded from the internet, with WINDOWS malware present. Unless the Mac user opted to boot into an old, unpatched version of Windows, without any anti-malware programs installed (dubious case), he wouldn’t be affected at all.
Should have included Lazlo in PA on my reply. Read the ENTIRE article. It clearly shows that Macs do have Mac viruses as well. Also as the user base grows they will become more targets of this malware.
Macs are malware vectors,
spreading disease wherever they go.
