When Comodo encounters an executable that isn’t in its whitelist, it will run the file in a quarantined environment. In theory, Comodo has a large enough number of legitimate programs in its database that this feature provides a security benefit with no usability drawbacks. Instead of allowing all files to run except those marked as malware, Comodo can block every application that isn’t in its whitelist. I looked at some of the most useful-looking ones here. To its credit, Comodo is jam-packed with useful features. Additionally, it appeared to terminate its own components as if they were malware, casting doubt on its effectiveness.īased on the relative lack of unbiased information on Comodo’s security performance, it's difficult to make a well-informed judgment. In my testing, I found that it incorrectly identified Lavasoft Web Companion as malware. Advanced or customized threats might slip through the cracks. This tells you that its heuristics engine isn’t quite up to snuff. PC Magazine found that Comodo handled hand-modified ransomware samples poorly. AV-Test, an independent antivirus testing organization, reported that the premium version of Comodo’s security suite performs well on real-world malware. Comodo is not one of the most popular antivirus suites, so test results for it are few and far between.

Independent antivirus test labs frequently compare antivirus programs.
