Antivirus protection is software that detects and deflects malware that could infiltrate company’s digital systems to steal, abuse or corrupt data. It can be used to protect various devices like laptops, desktops, mobile devices such as tablets and smartphones as well as connected home gadgets such as smart TVs and printers.

Modern antivirus products employ multiple detection methods to block one virus. One of the most popular methods is detection based on signatures. This involves keeping an array of distinct code snippets, also known as malware signatures and analyzing files to find matches. However, if attackers modify existing malicious code enough to be unable to be detected by these signatures, they are considered polymorphic and requires more advanced detection methodologies.

Heuristic-based detection is an advanced technique. It aims to identify malware by identifying patterns that are unique to malicious code, for example, changing and deleting large amounts of data, changing the settings of other programs, or remotely connecting to computers. Heuristic-based security detection can lead to false positives and fatigue.

Choose a strong antivirus program that is able to manage polymorphic malware, ransomware, memory attacks and other advanced threats. It should be simple to install on a wide range of devices, including Macs as well as Windows PCs and operate on various operating systems. It shouldn’t use too many system resources because this can cause the device to slow down, or even crash.
