Linux

I think we should be proud. Linux is finally large enough to at least sort of get "hit" by a malware campaign, and it demonstrates the ease with which thousands of infected packages can be cleaned, because they are centralized to a few repositories. M$'s only bet would be to update Defenders' index and cross fingers that the signature doesn't change.
Windows malware is always way out of control of M$, while that's also the norm of uninfected programs.
Almost all Linux programs are by design installed from a central repo.
