There has been plenty of people here who have claimed that Linux and open source provide an architecture which is by design more resilient against malware than proprietary solutions.
It is. That is why a Linux malware get to be news whereas yet another Windows malware does not register above the noise as news because there are so damn many of them. The same thing with the Bash, GnuTLS, OpenSSL etc vulnerabilities. "More resilient" does not mean immune - claiming immiunity would just be silly. News of Critical Vulnerabilities in Windows are about as frequent as every Patch Tuesday.
