I'll take a persistent BIOS infection with extra rootkit, please
The 100-line virus these guys created is for demonstration purposes only — they don’t plan to unleash it on the world. Piggybacking on a helper virus that gains admin privileges and then flashes the BIOS, this sub-virus would stay alive even if you changed out every other piece of hardware. The only way to fix it would be to re-flash the BIOS with a non-infected computer.
Sounds awfully nasty. Our advice? In real life as in cyber life, don’t accept attachments from strange men.
