Antivirus protection is software that detects and deflects malware that can penetrate a company’s electronic systems to steal, misuse or corrupt data. It is able to safeguard a variety of devices, including laptops, desktops and mobile devices, such as smartphones and tablets and even connected home gadgets like smart TVs and printers.
Modern antivirus applications typically employ multiple detection methods to avoid a single infection. Signature-based detection is an extremely popular method. This involves scanning files for matches and maintaining a database that contains distinct code snippets, referred to as malware signatures. However, if attackers alter existing malicious code enough to block detection by these signatures, it’s considered polymorphic, and requires more advanced detection methodologies.
Heuristic-based detection is a more advanced method. It attempts to identify malware by recognizing patterns that are specific to malicious code. For example, changing and deleting large quantities of data, changing settings for other programs, or remotely connecting to computers. Heuristic-based security detection can lead to false positives and fatigue.
Look for a virus protection software that can deal with ransomware and polymorphic malware. It should also be able to manage memory attacks, memory attacks and other advanced threats. It should also be easy to install on a wide range of devices, such as Macs and PCs, and work on various operating systems. Also, it should not use up too many system resources, since this could slow down the performance of an individual device, and even cause computer crashes.
