Do you have any idea what you're talking about, because I can't figure it out?

It seems that you need to do some basic research into what constitutes
malware and how the different kinds work.

Fundamentally, no, a Windows virus cannot infect anything other than a
Windows system.

Trojan horses do not "infect" anything, technically speaking.

What the heck is a "multi-threat infection" and how and what kind of
malware "infect[s] Windows directly from the wild?"  What does that
mean?
