What is ClamAV?
ClamAV is a free and open-source antivirus software and a cross-platform antivirus toolkit. Its primary purpose is to detect various kinds of malicious software, i.e. viruses, worms, trojans, rootkits, and many other forms of possible threats to your system.
The ClamAV antivirus provides a command-line interface for scanning your filesystem (files and directories) and also includes numerous tools for email filtering, automatic signature updates, and other functions. A lot of applications use ClamAV, mostly Internet gateways and mail servers, as a safety measure for scanning incoming communications and stopping malware distribution.
ClamAV was created by Tomasz Kojm at the Warsaw University of Technology in Poland in 2001. Afterward, ClamAV has been widely accepted by organizations and individual users, as it was made available for use, distribution, and modification under the GNU General Public License.
This article helps you understand what is ClamAV and why you should consider installing it on your system.
Is ClamAV Effective?
Considering the fact that ClamAV is an open-source software, it is clear that it possesses certain flaws. Most importantly, real-time protection is available only on Linux systems. Real-time protection is a crucial feature against zero-day attacks.
Besides real-time protection, there are no cyber security experts employed that would check if some of the updates added by the users are not, in fact, malicious and safe to be added to the ClamAV database. In fact, one of ClamAV’s key features is signed signature databases that protect users against such attacks, but having an expert employed would greatly enhance ClamAV database protection. ClamAV database is a virus database that is regularly updated with newly discovered threats and enables ClamAV to easily detect the threat.
On the contrary, the biggest upside of ClamAV is frequent updates. Sometimes, updates are released multiple times per day. If we take that information into account, there is a high possibility that ClamAV will actually detect a threat.
ClamAV provides a multi-threaded virtual scanner, a tool for automatic virus database updates, and a command-line scanner. If you take into account that ClamAV can detect millions of various threats, you understand that ClamAV provides effective antivirus and anti-malware protection.
ClamAV consists of three primary components.
1. ClamAV engine - the core component of the ClamAV antivirus that is responsible for performing malware detection.
2. ClamAV database - the component that is most frequently updated, and it contains the virus signatures used to detect malware.
3. ClamAV frontend - frontends are the applications that provide a user interface for ClamAV. Several frontends are available for ClamAV. Some of them are ClamTK and Clamdigger.
