Cross-platform malware in Viruses, Spyware, Adware Posted September 12, 2016 · Edited September 12, 2016 by terry1966 · Report reply there is no more "popular" os out there than linux. it runs nearly everything including i bet the server your seeing this forum on. so i'm not really a believer in the more popular argument. like we all know though the biggest problem with any os is not the os itself (especially now windows follows a more secure way of operating by default.) but the idiot using it.
