Antivirus protection software blocks malware that could infiltrate the electronic systems of a company to take over, misuse or destroy data. It is able to safeguard a variety of devices including laptops, desktops and mobile devices like smartphones and tablets and even connected home devices such as printers and smart TVs.
Modern antivirus products employ multiple detection methods to block one virus. Signature-based detection is the most common method. This involves maintaining a database of distinct code snippets, also known as malware signatures and scanning files to discover matches. If attackers alter malicious code to be able to evade detection by signatures, they’re considered polymorphic and require more sophisticated detection techniques.
A more advanced method is heuristic-based detection. It tries to identify malware by recognizing patterns that are unique to malicious code. For example, changing and deleting large amounts of data, changing settings for other programs, or connecting remotely with computers. Heuristic-based security detection can lead to false positives and fatigue.
Look for a powerful antivirus program that is able to handle ransomware, polymorphic malware memory attacks, and other advanced threats. It should also be easy to install across a broad range of devices, which includes Macs and PCs, as well as work with various operating systems. It should not consume too many system resources as this could cause a device to slow down, or even crash.
