Linux isn't invulnerable. Don't say it is.
Every month or so, I find some blog or forum post telling the world that because Linux is so hardcore, there's very little chance of it getting any malware. As you can probably tell from the title, I disagree and want these people to recognise why their arrogance is dangerous.
The prompt for this entry was a post on Linux Journal: Linux, Where Crapware Goes to Die. You can condense the whole thing into three sentences:
1. Linux is harder to infect than Windows because you run as a non-privileged user.
2. Linux makes it more simple to disinfect due to a more transparent install process and no significant binary registry.
3. Repositories (that, for example, apt-get uses) are free from scummy apps thanks to everything being vetted through testers and maintainers.
