Effectiveness.
Historically, ClamWin Free Antivirus has been criticized for its poor detection rates and slow scans compared to other antivirus programs. In past evaluations, it struggled significantly in detecting various types of malware. For example, in 2009, ClamWin Free Antivirus failed to detect almost half of the trojan horses, password stealers, and other malware in AV-TEST's "zoo" of malware samples.
In the 1–21 June 2008 test performed by Virus.gr, ClamWin Free Antivirus version 0.93 detected 54.68% of all threats and ranked 37th out of 49 products tested, with the highest-ranking product detecting over 99% of threats. Similarly, in the 10 August-5 September 2009 test, ClamWin Free Antivirus version 0.95.2 detected 52.48% of all threats and ranked 43 out of 55 products tested, where the best performer scored 98.89%.
These evaluations are over a decade old. In recent years, ClamWin has seen several updates, though comprehensive independent test results from major antivirus testing organizations are scarce. Users should consider that ClamWin remains primarily a free, open-source antivirus solution, which might not offer the same level of comprehensive protection as some commercial products.
Despite the absence of new effectiveness information from major testing organizations, ClamWin continues to be a popular choice for users seeking a free and open-source antivirus solution. Users looking for more robust protection may need to consider additional security measures or alternative antivirus solutions.
In 2011, cNet gave ClamWin Free Antivirus a rating of 4 out of 5 stars, acknowledging its user-friendly interface and regular updates but also noting its relatively slower scanning speeds and lower detection rates compared to other antivirus software.
