Any time you open or download a new file, an antivirus program will scan the files for viruses and other harmful executables. Almost every free anti virus software today features multiple scanning detection processes. The most basic detection process is called “specific detection.” It works by scanning a file for various sets of characteristics and checking these characteristics against a list of already known malware. This process is an essential component of an antivirus software, and essential for every free PC antivirus, but it is also easy for cybercriminals to evade. All a cybercriminal must do is modify the malware code slightly to render it undetectable.
The top free antivirus, Comodo Antivirus, does not rely only on specific detection. Comodo also uses heuristic detection and containment to ensure that even unknown malware cannot compromise our users’ computers. Heuristic detection is a method of analyzing a file to determine if it contains suspicious code. If suspicious code is detected then the antivirus deletes the file or recommends it for containment. Files run in Comodo containment are kept in a sandbox environment, separate from your operating system. 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.
