Antivirus protection is software that detects and blocks malware that could infiltrate company’s digital systems to steal, abuse or destroy data. It can be installed on a wide range of devices including laptops, desktops and mobile devices like smartphones and tablets and also on connected home devices like smart TV or printer.

Modern antivirus products employ multiple detection methods to ward off one virus. A common method is signature-based detection. This involves scanning files for matches and maintaining an inventory of distinct code fragments, also known as malware signatures. If hackers alter malicious code in order to avoid detection by signatures, they are considered polymorphic and need more sophisticated detection techniques.

A more sophisticated method is heuristic-based detection. It attempts to identify malware by identifying patterns that are specific to malicious code, for example, 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 should be carefully calibrated to be sure that false positives are not missed.

Choose a strong virus protection program that can handle ransomware, polymorphic malware memory attacks, and other advanced threats. It should be easy to install on a wide range of devices like Macs and Windows PCs. It should also operate on various operating systems. Lastly, it should not consume too much system resources, as this could reduce the performance of a single device http://www.antivirussolutions.net/fixed-word-cannot-complete-the-save-due-to-a-file-permission-error/ or even lead to computer crashes.
