content: Linux does have viruses out there, but they are mostly targeted to server deployments that haven't had security patches installed.  Desktop linux could get viruses too, but desktop installs tend to get regular security updates installed and the user base is such a small target that also tends to be somewhat more tech-savvy thus more difficult to trick into installing malware.  It isn't worth it to write malicious code for.  I used to get viruses all the time in Windows and had to re-install regularly to get my computer working again.  I finally got fed up about 15 years ago and decided to try Linux.  I have never had a virus since.
