The press doesn’t pay too much attention to malware because it’s nothing new and people don’t want to read about it. There have been millions of Windows viruses. Do you really want to read an article about how the 20,461,316th virus is now making its rounds?
If you read computer related articles a lot though, you’ll find that viruses/malware are reported quite often. The big things in articles these days are the two things that the OP specifically mentions, Apple and tablets. Both of these originally benefited from security through obscurity. Most of the viruses/malware out there were Windows based, because most computers were Windows based. If you are going to go through the bother of writing a virus, why would you take all of that effort to infect only a tiny number of machines? You wouldn’t. You’d target the most machines possible, so you’d target Windows.
This has given the impression, especially among Apple users, that their computers are immune to viruses. Hey, you got an Apple, you don’t need to worry about Viruses. That’s Windows stuff. That kind of attitude has left Apple computers and tablets of all brands very much unprepared and unable to handle virus and malware threats, and as a result, the big boom in viruses and malware these days is on Apple, tablets, and phones.
In the Windows world, viruses and malware are constantly being released, but they don’t tend to be as devastating as they used to be, probably due in large part to Windows getting more secure and Windows users getting a bit smarter about viruses and malware.
In the Apple world, in tablets, and in phones though, viruses and malware are definitely not waning. Quite the opposite. They are all very much on the rise.
