Hacking Windows boxes gives more bang/buck because the goal of virus writers is to spread their ilk. A perfect Linux virus would span at most 20% of installed systems now. That does not look attractive ?! 2. Windows libraries have countless undocumented 'shortcuts' meant to speed up the system. The shortcuts circumvent many system security features (such as never running any processes that interpret network data with root privileges). This means that the first breach means a compromised machine, with immediate root access. This is not the case on *nix where compartmentation is very strict. A breach on a *nix machine usually exposes a very small set of features because of this. 3. When you say *nix you actually say one dozen (two dozen ?) different platforms, operating system versions, and setups. There is no way to write a virus that efficiently attacks all of these. It would have to be the size and complexity of Mozilla. 4. *nix users actually do have a clue as to what they are doing most of the time, as opposed to the competition which is limited to clicking on message boxes which usually say such tremendously helpful things as 'your system is on fire. [ok] [cancel]'. This is due to log messages, and access to tools that can pick the system's brains and tell what's wrong. This means a capability to react, even if not everyone knows how to use it.
