A good protection is NOT an impossible dream! :-)

it's because M$ is the most OS used. If Linux was used like M$ you will see a lot of cracks for Linux.

Exactly!

And that's also the reason why there are more virii, trojans and worms for Microsoft Windows.
But every nasty bastard obviously thinks he'd have to blame Microsoft, and not all the dummy users, or the coders of such malware.
If I'd code a trojan, it would just make sense to do so for a widely used operating system, and not for a system just a few thousand folks use.
So it's definately NOT Microsoft's fault!
