Antivirus protection is software that detects and deflects malware that can infiltrate a business’s digital systems to steal, abuse or destroy data. It is compatible with many different devices including laptops, desktops and mobile devices, such as tablets and smartphones and also on connected home devices like smart TV and printers.
Modern antivirus products employ various detection techniques to stop one virus. Signature-based detection is the most common method. This involves maintaining an array of distinct code fragments, also known as malware signatures, and then scanning files to find matches. However, if hackers alter existing malicious code enough to avoid recognition by these signatures, it is considered polymorphic, and requires more advanced detection techniques.
Heuristic-based detection is a more advanced method. It tries to detect malware by identifying patterns that are unique to malware, such as altering and deleting large amounts of data, altering the settings of other programs or remotely connecting to computers. The use of algorithms to detect malware can lead to security alert fatigue and must be carefully crafted to prevent false positives.
Look for a robust antivirus program that is able to deal with polymorphic malware, ransomware, memory attacks and other advanced threats. It should be easy to install on a wide range of devices, including Macs and Windows PCs. It should also run on different operating systems. Additionally, it shouldn’t consume too many system resources, as this can hinder the performance of a particular device or even lead to computer crashes.
