>The rather low popularity of GNU/Linux is the main reason why there are not
many viruses/troyans/worms targeting it.
I disagree on this point. Gnu/Linux's popularity is everything but low and
there is certainly great incentive to write malware for it, there are
hundreds of thousands of servers cracking which would be extremely profitable
But you have nailed it completely when you say
>Then, there is the fact that GNU/Linux users usually not run as root, so the
vulnerability must allow privileges escalation to be actually dangerous.
Logic has it there are no viruses in the wild because of the great variety
of distributions and packages versions and especially because as you point
out writing a proper malware for GNU is no easy game.
dat my 2.15 cent..
