In before all the stupid replies that Linux cannot be hacked.
I suppose there could be some people stupid enough to say that, but I haven't seen much of it (unless you count obvious troll posts). In fact, a misconfigured linux system is one of the easiest to hack -- but we're discussing malware, not hacking. Since most linux distros are using repositories for all the third-party software (vs non-tech users zooming around the web downloading "10,000 similies!") malware for linux is pretty darned rare -- much more so than windows or os x. Unless, of course, one counts all the android trojans -- I don't because to me android is a completely unique OS that happens to use some linux code.

The fact is, whether you're an Appalachian snake handler or a CS PHd, you have many beliefs and not all of them are rational. Now, would you like me to fetch you a stepladder, so you can climb down from that high horse?
It is masked but always present. I don't know who built to it. It came before the first kernel.
