![]() ![]() Heuristics is about detecting virus-like behavior or attributes rather than looking for a precise virus signature that matches a signature on the virus blacklist. Files run in Comodo containment are kept in a sandbox environment, separate from your operating system. If suspicious code is detected then the antivirus deletes the file or recommends it for containment. Heuristic detection describes the method of analyzing the code of a file to determine if it contains code commonly found in malware. ![]() Modify the code slightly, and the malware is rendered undetectable.Ĭomodo Antivirus also uses heuristic detection and containment to ensure that even unknown malware cannot compromise our users’ computers. Like a wanted outlaw in the old west, a cybercriminal can disguise a piece of malware to avoid detection. This process is executed quickly and is an essential feature of an antivirus software, but it is also easy for cybercriminals to evade. Specific detection works by scanning a file for a specific set of characteristics and checking these characteristics against a known list of malware. This is what most people think of when they think about how an antivirus works. The most basic detection process is known as specific detection. Most modern antivirus programs feature multiple scanning detection processes. Caveat emptor indeed, and use that 30 day evaluation period to make up your mind about purchasing, but 'no refunds' is hardly an uncommon policy where software is involved.Whenever you download or launch a file, an antivirus program scans the file for malware. ![]() I don't use HRD and I'm not associated with the company, but I can clearly see why they won't issue a refund once a license is delivered. I suppose HRD could institute that kind of setup, but my experience with such is that they generally work poorly, result in security complaints that the software is phoning home, cause problems if you move the software from one machine to another, and are just generally an expensive pain in the neck for companies to support and maintain. Unless you have some cumbersome networked license server scheme where the software phones home every time you run it to see if the license is valid, you have no way to know (other than via your own good faith) that the person who demanded a refund actually discarded the license and is not running the software. The company I work for won't give refunds for licenses either, once they are cut and sent out. ![]()
