Antivirus protection software detects and deflects malware that can penetrate a company’s electronic systems to steal, misuse or destroy data. It can be installed on various devices such as laptops, desktops, and mobile devices such as tablets and smartphones, as well as connected home devices such as smart TV and printers.
Modern antivirus applications employ multiple detection methods to ward off one virus. One common method is the signature-based detection. This involves keeping a database of distinct code fragments, also known as malware signatures, and scanning files to find matches. If attackers modify malicious code to be able to evade detection by signatures, they are considered polymorphic, and therefore require more advanced detection methods.
A more sophisticated technique is heuristic-based detection. It tries to detect malware by identifying patterns that are unique to malicious code, for example, altering and deleting large amounts of data, altering the settings of other programs or remotely connecting to computers. The use of algorithms to detect security threats can result in false positives and fatigue.
Find a reliable virus protection program that can deal with polymorphic malware, ransomware memory attacks, and other advanced threats. It should also be easy to deploy across a wide range of devices, such as Macs and PCs, and run on various operating systems. It shouldn’t use excessive system resources since this can cause the device to slow down or even crash.
