DOWNLOAD : Anti-virus For Linux.

Linux is no longer immune to security threats, All computer systems can suffer from malware and viruses, including Linux.

Linux operating systems have been considered less vulnerable than Windows systems for many years but the myth that they are immune to virus attack is completely false.

It is still recommended that Linux users have antivirus software installed on Linux systems that are on a network or that have files being transfered to the device. Some users may argue that antivirus software uses up too much resources. To better understand antivirus programs, it may be beneficial to understand malware itself.

The Linux platforms early low instance of attacks was primarily due to the lack of root access required for malware to infiltrate the system, the Linux communitys ability to quickly patch vulnerabilities, and the low adoption rate of Linux in the corporate network. This made Linux a lower priority target for the writers of malware.

There are a number of anti-virus applications available which will run under the Linux operating system. Most of these applications are looking for exploits which could affect users of Microsoft Windows.Virus scanners are security applications that search the system for malware. The scanners look for certain patterns of code or specific characteristics of malware. Depending on the threat potential, virus scanner, and settings, the malware may be deleted instantly or the user will be asked what to do with the malicious software.

• ClamAV(FREEWARE).

ClamAV is an open source (GPL) antivirus engine designed for detecting Trojans, viruses, malware and other malicious threats. It is the de facto standard for mail gateway scanning. It provides a high performance mutli-threaded scanning daemon, command line utilities for on demand file scanning, and an intelligent tool for automatic signature updates. The core ClamAV library provides numerous file format detection mechanisms, file unpacking support, archive support, and multiple signature languages for detecting threats.

Latest ClamAV® stable release is: 0.98.1 , download from :
