Antivirus protection software blocks malware that can infiltrate electronic systems of a company to take over, misuse or damage data. It can be used to safeguard a variety of devices including laptops, desktops, mobile devices such as tablets and smartphones as well as connected home devices such as printers and smart TVs.

Modern antivirus software typically employs multiple detection techniques to prevent the spread of a single infection. One method that is commonly used is a signature-based detection. This involves scanning files for matches and keeping a database with distinct code fragments, also known as malware signatures. If attackers alter malicious code to evade detection by signatures, they are considered polymorphic and require more sophisticated detection methods.

A more sophisticated technique is heuristic-based detection. It tries to detect malware by recognizing patterns that are unique to malware, such as modifying and deleting large amounts of data, changing 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 antivirus program that is able to handle ransomware, polymorphic malware, memory attacks and other advanced threats. It should be simple to install on a wide range of devices like Macs and Windows PCs, and be compatible with different operating systems. Additionally, it shouldn’t consume too many system resources, as this can hinder the performance of a single device, and even cause computer crashes.
