  (By analogy with biological viruses, via SF) A cracker program that searches out other programs and "infects" them by embedding a copy of itself in them, so that they become Trojan horses. When these programs are executed, the embedded virus is executed too, thus propagating the "infection". This normally happens invisibly to the user. 
  
 These days, "[Virus]" is an umbrella term for any kind of malware, be it an actual virus, a worm, a trojan horse, or any other malicious piece of code. The boundaries between the types are blurring, anyway. 
  
-While [Linux] and other [Unix] derivatives are by no means immune from malware, both the sloppier system design and the popularity and sloppy administration of MicrosoftWindows systeams means that [Linux] [Virus]es are a negligible minority -- you can [read about this in more detail | http://linuxmafia.com/~rick/faq/index.php?page=virus]. However, while [Linux] is resistant, it is not immune. You still need to pay attention to [Security | SecurityNotes].

 Of course, if you run MicrosoftWindows programs on [Linux] in an emulation such as [Wine] or [VMWare], that isolated environment is still susceptible, even if the system around it goes unaffected. However, just as any normal application won't necessarily run well under emulation, so too may [Virus]es not be able to. [Practice confirms this. | http://os.newsforge.com/article.pl?sid=05/01/25/1430222] 
  
 It is paradoxical only at first sight that Linux is a popular system on which to run [Virus] scanners such as [ClamAV]: there is no danger of infection from [Windows] viruses, so [Linux] is an ideal environment for sorting them out.
