But if you know what you're doing, it's hugely useful, and tramples most of the 'extras' you'll get elsewhere like the endless 'file shredders' into the ground. Comodo's Settings dialog rounds off the program with something for everyone. Beginners can choose a new theme for the interface, or disable update checking when the system is running on batteries. But more experienced types can customize how scans work, create new scan types, tweak the HIPS, and generally get involved in most of Comodo's low-level operations.
Comodo Free Antivirus isn't assessed by most of the independent testing labs, but AV-Test checks Comodo's Internet Security, and the results are interesting. The Usability element of the test counts false alarms raised by an antivirus. Comodo Antivirus incorrectly blocked three actions of legitimate software, but the industry average is two, so that's hardly a big deal.
And it didn't falsely detect any legitimate website or software as malicious, an excellent record. What's much more important is the protection you get, and we decided to check that further by matching Comodo against our own custom ransomware simulator. As we've developed it ourselves, Comodo Free Antivirus wouldn't be able to detect it from its file signature alone, making this a more interesting test of the product.
We launched the simulator, and accepted Comodo's default option to run the program partly isolated, with limited rights to our system. The simulator ran to completion, but because it was mostly sandboxed, not one of our test files had been touched. That was impressive, especially as the same approach will block most other threats, well-known or brand new. But keep in mind that it does still rely on human intervention, and the user correctly deciding which applications are safe, and which need sandboxing.
That's fine for experts, not so much for security novices, or anyone who wants the antivirus to decide everything for itself. A powerful antivirus tool with some unusual and advanced features. The interface can be complex, though, and you'll need real technical expertise to get the most from the program.
