That's because Linux only has a very small segment of the market. If Linux gains a larger market share, then the idiots that write viruses will begin to write viruses for Linux.


Anyone who makes that claim simply doesn't understand how the vulnerabilities occur. When you look at web servers, over 75 % of them run Apache on Linux or Unix, yet it's the servers running IIS that get clobbered. Why is this? Take a look at the various security methods between the two systems, such as in Linux or Unix, in order for a virus to run, it has to be deliberately made executable. It simply won't run otherwise. Then, since Linux users rarely run as root, even if a virus some how takes hold, it's damage is limited to only those areas that the user has write access. There are many other reasons. One of my favourites involves the Netscape vs Microsoft case, where Netscape was suing MS over the forced bundling of IE on all Windows computers. At that time, IE was just another application, just like Netscape. However, MS claimed in court that IE couldn't be removed because it was part of the operating system and sure enough, next version of Windows (W98 IIRC), IE was deeply embedded in the operating system, to the point that IE vulnerabilities became OS vulnerabilities and malware would then have run of the system. The list of reasons for MS security weakness is a long one and has little to do with number of targ^H^H^H^H users.
