Bootkitty?
However,
you can already patch your BIOS to become secure again! :)
All in all, Windows security is a joke compared to Linux’s.
bootkitty wasn’t implemented ever and if you use GUID Partition Table and your bios is set to uefi without csm, it can’t affect you, since Bootkitty embeds itself into the Master Boot Record and there exploits the LogoFail vulrenability (this was already patched btw) with as far as i remember, a self-extracting steganographical bitmap image for arbritary code execution to bypass Secure Boot with injecting face certifications to Moklist. Also, it only runs on select devices, far from all Linux systems are vulrenabe.
Windows security is… fine? It could be better, but it’s pretty much on par with linux security. Both have their vulns, but they’re both also able to be secured enough that most (if not all) major data breaches are via phishing or other social engineering attacks, not solely software exploits. There’s lots of fodder for the Linux vs. M$ debate, but this one is maybe a bit out of date.
If you actually dig deeper into the Linux security topic, you’d find out that Linux is actually not very secure. GrapheneOS developers made quite a lot of posts on what Linux distros (and the kernel) are missing in terms of security. A lot of “Linux security and the lack of viruses” rides on the waves of “there is hardly any point of creating malware for a system with such a small user base, plus you have to consider the fact that people knowledgeable enough just to install a Linux distro would be a bit more careful about their computers than the average Joe”.

Actually the whole world runs on linux, Windows is mostly the low level consumer end.
Which makes your argument true for a certain segment of malware (the cheap low tech stuff more akin to scams etc targeting people en mass but expected to have a low return), but not actually for the parts where the money is that justify elaborate malware and hacks.
