I don't think Windows is that bad. The popularity of Windows users is much more than Linux because it is easy to use, so most hackers dedicate their malware to Windows.
Let's
compare: there are 1.57 billion Windows users, 48 million Linux users and 2.26 billion Android users. If popularity would be the main thing, there would be more malware for Android. But Android is Linux-based.
I can only conclude Windows is indeed
that bad.
