Antivirus Software Must Be Kept Updated

One important thing to consider about any antivirus software is the frequency of the updates. Cybercriminals release new Trojans and computer viruses every day.

Some of the malicious software targets computers in large numbers. Without regularly updating an antivirus, it won’t be a match to the newly released viruses.

There have been many open-source antivirus software released in time past, but many of them have dormant and un-maintained. For instance, we excluded the following antivirus projects because they’re old.

Best Open Source Antivirus Software

Moon Secure Antivirus

The latest download of this antivirus is dated 2016-09-24. Even though the program uses the ClamAV engine, it hasn’t been updated recently and can’t combat newly developed computer viruses.

OpenAntivirus Project

The last virus definition for this antivirus was from May 30, 2004. So, the antivirus cannot protect your computer from the latest viruses on the internet from 2005 till date.

Armadito Antivirus

The last source code commit was four years ago, on Sep 12, 2017, showing that developers have abandoned it.

Anyone downloading Armadito antivirus might be exposed to security vulnerabilities.

One reason for the lack of updates on some open-source antivirus programs is that they don’t use signature-based detection to identify current threats. Commercial antivirus companies rely on signature-based detection to quickly identify current threats and update their programs to combat them.

Also, no FOSS antivirus programs are using a heuristic engine. Heuristic virus detection is capable of looking past known virus signatures but complicated. It is a method of using algorithms to identify the behavioral patterns of a particular virus during testing.

Many recent computer viruses can’t be detected through a typical scan. The developers use powerful encryption to conceal them. Given the advanced and persistent nature of current threats, heuristics is becoming a must for open-source antivirus programs if they must remain relevant.

Supports your computer or mobile operating system

Before downloading a FOSS antivirus program, check the operating systems it can protect. If your computer or mobile operating system is not listed, then it’s not compatible with it.

Cybercriminals create sophisticated malware such as spyware, ransomware, viruses, and adware targeting devices on different operating systems. Your choice of antivirus program must be designed for your devices’ OS and tailor-made to suit its computing behaviors.

Some open-source antivirus programs such as ClamAV are cross-platform, meaning they can work for Windows, Android, or even MAC. Others are specific and only available to certain OS or platforms. They might work for Mac but not Windows.

However, the main open-source antivirus project is used in several downstream projects. For instance, many downstream projects work with virus definition from ClamAV.

ClamAV

Clam Antivirus is one of the best open-source antiviruses that is frequently maintained and updated every four hours. It detects different kinds of malware and Windows viruses using in-built signatures.

ClamAV runs across multiple operating systems such as Windows, macOS, Solaris, Linux through its third-party versions. It is light and doesn’t slow down your device but somewhat improves its performance.

History & Ownership

ClamAV was created by five developers and sold to Sourcefire. The company acquired the trademarks & copyrights to ClamAV and announced it on Aug 17 2007. Afterward, the developers joined the Sourcefire Vulnerability Research team.

In July 2013, Cisco acquired Sourcefire, and the research team became part of Cisco.

Activity & Technology Used

ClamAV is actively maintained and updated by the Cisco Talos. The program has 46 contributors, including Micah Snyder. The ClamAV development team comprises 3 programmers, Andy Ragusa, Mickey Sola, and Micah Snyder.

ClamAV was written in C, C++, Assembly, Python, CMake, Yacc, etc. 85.5% of ClamAV codes were written in C language. 9.6% of the codes were in C++ programming language, CMake occupied 1.9% of the codes while Python, Assembly, Yacc and others were 0.8%, 0.9%, 0.4%, and 0.9%.

Effectiveness & Shortcomings

ClamAV uses signatures to detect malware. It detects viruses through their signatures or fingerprints. Virus signatures are bits of code or unique data that enable antivirus programs to identify them.

Signatures-based detec
