Most modern antivirus programs feature multiple scanning detection processes. The most basic detection process is known as specific detection. This is what most people think of when they think about how an antivirus works. Specific detection works by scanning a file for a specific set of characteristics and checking these characteristics against a known list of malware.
This process is executed quickly and is an essential feature of an antivirus software , but it is also easy for cybercriminals to evade. Like a wanted outlaw in the old west, a cybercriminal can disguise a piece of malware to avoid detection. Modify the code slightly, and the malware is rendered undetectable. Heuristic detection describes the method of analyzing the code of a file to determine if it contains code commonly found in malware.
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.
Laptops face all the same threats as desktops, from trojans, worms, ransomware, spyware, adware, etc. But in addition to these threats, laptops also face a unique vulnerability to plug-in attacks. Laptops running Windows, macOS, and Linux are all vulnerable to these attacks, which are executed by a cybercriminal compromising an unattended machine through a charger, docking station, or USB port.
To prevent falling victim to these types of attacks, users must install a laptop antivirus bundle that isolates unknown files entering the system.
