Avast, Kaspersky and so on sell trojans that compete against other, free, as in gratis, trojans in userspace. They have next to no interest in security as such beyond that scope.
Disclosure, worked there 15 years ago.
I think you can find more stuff like this through your own digging.
(In my dictionary, trojan allows remote control. Maybe I'm just old.)
Did the Crowdstrike thing earlier this year reach you? They sell a corporate version of this kind of trojan, and did a fuckup in an update, suddenly making a lot of people realise that someone else has control over their computers.
Edit: that came out way more condescending than I intentended
