The biggest one is ClamAV, with official virus databases as well as third-party databases and custom YARA rules.
Linux is pretty good at Virus protection by itself. But you can get ClamAv, or any of the big name Anti-Virus programs for it.

There are a HUGE amount of packages available in Linux. Thousands upon thousands. You have to keep in mind that even a program that, to you, is just one program, is actually made up of several packages. For example, if you want to install the VLC media player, you have to install a package called VLC, but also a package called VLC-NOX, VLC-Data, libvlc2, libvcdinfo0, etc...
No. There have been no wild Linux viruses in several years. There's no avenue for them to get onto a Linux system; most distros use secure repositories where only software compiled from source is available. No Linux email client launches attachments automatically, so you can't "accidentally" run a bad program, and programs run under a non-root account don't have the ability to modify other programs on the system.Antiviruses are useful on Linux in some situations and are available. If you regularly download files and share them with Windows users, an antivirus can help you to protect them. They do not do you any good personally, though.
The best (and perhaps usual) answer is to use an antivirus program. For Windows, there are hoards of antivirus programs available like McAfee, Norton, Kaspersky, AVG, K7, Quickheal, Avast!, etc. For Mac and Linux, there one AV software available called Clam AV (ClamAV.net).
Because some of them suck.
clamav - open source so fully free and no license needed. This started as a Linux anti-virus product but windows versions are available. www.clamwin.com
I personally use Avast but really it is not needed in Linux as you can't get infected with the M$ viruses ----- Panda Software has a free edition of it's Antivirus which runs on Linux.
Patches are usually released as updates to the affected packages.
To install the available packagesuse th RPM utalities in command prompt or add new program utalities in gui.otherwise if u want intall any other it should becompatable with Linux and u can userpm zip or tar utalities to intall it.
