Dynamic scanning: Also known as file emulation or sandbox testing, this process tests and analyzes a file’s behavior in a controlled environment to see if it behaves like a virus, and flags it if it does.

Rather than using a list of viruses as a reference to determine whether a device contains malware, heuristic virus detection spots viruses by identifying files with suspicious behavior or code infrastructure and flagging them as potentially dangerous. This is where heuristic analysis comes to the rescue. However, there are now so many new viruses - more than 300 million created per year - that this method is no longer as effective at catching malware. Signature detection compares computer code to a known list of viruses to identify whether a computer is infected.

Older forms of antivirus software used a method known as signature detection to identify specific viruses. How does heuristic virus detection detect a virus?

Let’s explore how heuristic analysis works as well as how you can use it to your advantage when hunting down malware. In the world of antivirus technology, heuristic analysis refers to the set of rules that antivirus software uses to detect potential malware on a device. Heuristic analysis is a problem-solving method that involves following rules and making educated guesses to reach a solution. This section will provide a deeper understanding of heuristic analysis to clarify how it is distinct from Heur.Invader and to help you feel confident using antivirus software to identify potential threats to your device. While some people refer to a novel virus identified through heuristic analysis as a “heuristic virus”, this can cause confusion as Heur.Invader is a specific virus that attacks your antivirus software’s heuristic analysis process.

That being said, the term "heuristic virus" is better suited to describe the specific virus Heur.Invader whereas heuristic analysis is an adaptive antivirus defense that discovers malicious code through educated guesses. The terms “heuristic virus” and “heuristic analysis” are often confused and believed to convey the same meaning - the processes used to detect malicious code and software.
