Antivirus protection software detects and blocks malware that can penetrate a enterprise’s digital systems in order to steal, misuse or destroy data. It is able to protect a variety of devices like laptops, desktops and mobile devices, such as smartphones and tablets and even connected home devices like smart TVs and printers.

Modern antivirus applications typically employ multiple detection techniques to prevent one infection. Signature-based detection is the most common method. This involves keeping a database of distinct fragments, also known as malware signatures and scanning files for matches. However, if attackers alter existing malicious code to block detection by the signatures, it is considered polymorphic, and requires more advanced detection techniques.

A more sophisticated method is heuristic-based detection. It attempts to detect malware by recognizing patterns unique to malicious code. For example, modifying and deleting large amounts of data, changing settings for other programs, or remotely connecting to computers. Heuristic-based detection may cause security alert fatigue and should be tuned carefully to prevent false positives.

Look for a powerful antivirus program that is able to manage polymorphic malware, ransomware memory attacks, and other advanced threats. It should be easy to install on all kinds of devices, including Macs as well as Windows PCs and run on different operating systems. It should not utilize excessive system resources since this can cause the device to slow down, or even crash.
