Antivirus protection is software that detects and blocks malware that can penetrate a company’s digital systems to steal, alter or destroy data. It is able to protect various devices including laptops, desktops and mobile devices, such as tablets and smartphones as well as connected home devices such as printers and smart TVs.
Modern antivirus solutions employ multiple detection methods to ward off a single virus. One common method is signature-based detection. This involves analyzing files for matches and keeping databases with distinct code snippets, known as malware signatures. However, if attackers alter existing malicious code to not be recognized by these signatures, it’s considered polymorphic and requires sophisticated detection methods.
A more advanced technique is heuristic-based detection. It aims to identify malware by identifying patterns that are specific to malicious code, for example, altering and deleting large amounts of data, altering the settings of other programs or remotely connecting to computers. Heuristic-based security detection can lead to false positives and fatigue.
Choose a virus-protection program capable of handling the polymorphic nature of malware and ransomware. It must also be able to handle memory attacks, memory attacks and other advanced threats. It should also be easy to install across a broad range of devices, which includes Macs and PCs, and run on various operating systems. In addition, it should not consume too much system resources, as this could cause a slowdown in the performance of a single device, or lead to computer crashes.
