quote: The Truth about Linux VirusesOne the biggest vulnerabilities of the Linux system are the users who have the misconception that it cannot be infected by computer viruses. Several people believe that any non-Windows system is secure and doesn't need the aid of additional software to ward off viruses. This is far from the truth and a major reason why more viruses are being written for the system.
quote: The RealityIf you are going to trade files in a Windows world, you'll need to scan those files for viruses. You won't get infected, but you may help infect someone else. There are two ways to do this:Run all the files through a server which checks for you. GMail, Yahoo mail, and Hotmail all have wonderful checking software.Check the files for viruses yourself.You can install a program called ClamAV. Install the package. It won't appear in the menu. Run it by getting to a command-line and type in "clamscan -h" to get some help on how to run it. If you really need to use a gui front-end and don't like the command-line then just install "clamtk". See the AntiVirus page for other antivirus packages and more detailed instructions.Even if you do not trades files with the Windows world it is worth staying reasonably well up-to-date with normal updating procedures. https://help.ubuntu.com/community/InstallingSoftwa...

Radatti All rights reserved.This paper is intended to inform the UNIX and computer communities about formally undocumented computer virus problems. My observation of these problems were made at heterogeneous UNIX network sites and confirmed by discussions with system administrators at other sites. I believe that these problems are not limited to UNIX or heterogeneous networks. Furthermore, I expect the problems to expand in complexity, scope and virulence.I have observed non-UNIX personal computers attached to a heterogeneous network that were infected with computer viruses originating from UNIX workstations. The UNIX systems were not the original point of entry for the viruses. The viruses were dormant while on the UNIX nodes and became harmful when they migrated to their target systems. The UNIX systems acted as unaffected carriers of computer viruses for other platforms of computers. For the sake of simplicity, I have coined the phrase "Typhoid Mary Syndrome" when describing this problem.
