Apple’s one of the strongest suites other than of course all the things that only apple does was its ability to boast its virus/malware proof OS.
Apple website boasted of “it doesn't get PC viruses” and “Safeguard your data. By doing nothing” are now “upgraded” to “It's built to be safe." and "Safety. Built in”. Apparently Microsoft is proud, because for once they can claim Apple took over their style of marketing. (See before and after changes right here)
Reason for this meek marketing rather than the usual boastful one: Its first immune system failure or rather a new virus that blew out Apple’s claims.
