[LAD] Linux Malware

Hey guys! This is an Offtopic question, really, but I wanted to ask people I know and people who are developers - what are the reasons there are (almost) no viruses on Linux? The typical argument is that there are not too much users. I generally do not agree with this argument and point to architectural reasons, number of distros, community reasons and the openness of the platform. Additionally, I even argue that the more users, the faster news about a potential risk spreads. However, several of my friends and colleagues at work who are long time Linux users have argued that in the end it is still the number of users, since no architecture is perfect and virus writers will find a way to penetrate the system and target all known distros. I am wondering if I am missing something. Does anyone on this list thinks that number of users does play more than a minor role? -- Louigi Verona http://www.louigiverona.ru/
