Ask an avid desktop Linux user if he or she (ok, he) uses an antivirus solution, and he won't give you an answer, he'll give you a sermon. And while his zeal might be inappropriate, his sentiment will be largely correct: Linux really doesn't need antivirus software. Android, with a smaller market share and simpler guts than most common Linux distros, has even less to worry about — which is why it's completely absurd for SMobile systems to release VirusGuard, the first antivirus software for the mobile platform.
