Antivirus protection software detects and deflects malware that can infiltrate a business’s digital systems to steal, alter or corrupt data. It is compatible with many devices including laptops, desktops and mobile devices such as tablets and smartphones as well as connected home appliances like smart TV or printer.

Modern antivirus solutions employ multiple detection methods to ward off a single virus. A common method is a signature-based detection. This involves analyzing files for matches and maintaining a database that contains distinct code snippets known as malware signatures. If attackers alter existing malware to not be recognized by these signatures, it’s considered polymorphic, and requires more advanced detection techniques.

Heuristic-based detection is an advanced method. It attempts to identify malware by recognizing patterns that are specific to malicious software. For example, changing and deleting large quantities of data, altering settings for other applications, or remotely connecting to computers. Security detection using algorithms can result in false positives and fatigue.

Find a virus protection program that can handle ransomware and polymorphic malware. It must also be able to handle memory attacks, memory attacks, and other advanced threats. It should be easy to install on a range of devices, including Macs and Windows PCs and run on different operating systems. It should not consume excessive system resources since this can cause a device to slow down or crash.
