Antivirus protection

Comodo uses same malware and virus detection techniques to all its Windows products. It applies Defence Plus Technology and Auto Sandbox Technology in order to detect and fight against various types of malware and malicious installs. In addition, all suspicious items are sent to the company’s cloud-based servers for further analysis. According to the independent German-based testing lab AV-TEST,[3] Comodo Internet Security detected 100% of zero-day malware attacks, including web and e-mail threats and 99.8% of widespread and prevalent malware discovered in the last month. The antivirus delivered only 1 false positive while downloading of legitimate software as malware during a system scan.

According to AV-TEST, the antivirus detection rates of the Comodo Internet Security application are nearly perfect.


Comodo Internet Security offers special features according to the package. Comodo Internet Security Free includes basic antivirus protection and security features such as Spyware Scanning, Anti-Rootkit, Anti-Spyware, Bot Protection, Memory Firewall and browsing protection feature called Secure Shopping that protects users while banking and shopping online. Paid Comodo Internet Security packages include more special features, Comodo Internet Security Pro in addition to basic features, also offers Unlimited Product Support, Unlimited Live Expert Virus Removal and $500 Virus-Free Guarantee, while Comodo Internet Security Complete also includes 50 GB Online Storage and Backup and 10BG TrustConnect WiFi Security.

System-performance impact

Comodo Internet Security’s system-performance impact was also tested. According to the independent AV-TEST testing lab, the application had a relatively mediocre system hit. It scored 5.5 out of 6.0 in the performance section, as it slowed down the system while launching popular websites by 6%, the download of frequently-used application, by 1%, the launching of standard software programs by 15% and slowed down the installation of commonly-used programs by 35% while working in the baseline.

Scanning performance

Comodo offers users a full scan, a quick scan, a rating scan that checks commonly infected areas and a customized scan. The scans work smooth and quick, without causing any system lags or interruptions.

User interface

The basic look of Comodo Internet Security is very clear and easy to understand. All the main features are accessible from the main interface window. The subsections are informative and include a lot of more at-a-glance data. Comodo provides users all options and information in a well-organized way. The interface is bright and modern-looking and also includes a drag-and-drop area to scan files and folders for viruses. What we did not like, Comodo requires you to install unwanted software and change your default browser’s search engine.
