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.
Considering that belief is the opposite of thinking
That's an interesting belief you've got there...
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?
