On the one hand, I don't wish to sound alarmist. Linux is arguably
already the top OS out there. (Your forgetting all those c1u31355
Android cell phone users.) Lots of hackers would be interested (and
monetarily compensated) for hacking celb phones, so it's not like it's
not a target. Still, the viral population remains an order of magnitude
less for the various flavors of Nixen OSes.

However, if you do want the list of malware, look at the Wikipedia
article for Linux_Malware. There's a list at the bottom. They're out
there.
