Often, even if we do catch a virus, it's not so difficult to eradicate it using installed anti-virus—but if your system has been crippled, try using Linux to scan the drive for viruses instead. As any Linux veteran knows, one of Linux's greatest uses is fixing unbootable drives—recovering files, deleting files, and even killing viruses.

Estimates vary, but generally it is believed that there are 100 to 500 Linux viruses out there. The tiny number of Linux viruses that do exist have never resulted in a significant outbreak. In comparison to the plethora of viruses and worms in Windows-based platforms, the volume of Linux viruses is insignificant. So this leads us to two questions: why are there so few Linux viruses and are Linux anti-virus tools necessary?

Just because you use Linux, it doesn't mean your computer doesn't have viruses or worms. Virus is a catch-all phrase, and BitDefender's designed to catch them all - from executable viruses, script viruses, macro viruses, to backdoors, trojans, spyware, adware, diallers, and more.

One of the most frustrating problems with setting up any mail server is the configuration required for anti-virus protection and Spam checking. Amavisd-new provides an excellent tool to help in setting that up. This is a step-by-step process in providing your mail server, the example is Ubuntu 8.10, with the ability to scan all incoming mail for viruses and Spam.

If Linux is hardly affected by viruses, why do system administrators use anti-virus software on their Linux email servers? Because an anti-virus scanner on a mail server can serve as another level of defense for Microsoft Windows desktop users.

After having travelled through the virus infested land of Windows, new Linux converts often have queries about viruses on their Linux systems. Here I will demystify all those queries related to Viruses, Antivirus software’s etc once & for all.

In the most part, Linux is engineered in a fashion that makes it hard for viruses to run. Also, because more PCs currently run Windows, it is more worthwhile writing viruses for the Windows platform. However, there are many reasons you might want a virus scanner on your Linux PC:

While there is no excuse for inattention and lack of knowledge, the fact is that there are Linux virus's (viruses, virii?) and there will be more.

Historically, there have been some [gnu/linux effecting viruses]. And there are browser exploits, of course, that no operating system is completely immune from. However, viruses, as we think of them in the Windows world, are highly unusual.
