Antivirus protection software detects and blocks malware that could penetrate a enterprise's digital systems in order to steal, alter or corrupt data. It can be installed on many devices such as laptops, desktops, and mobile devices, such as smartphones and tablets, as well as connected home appliances like smart TV or printer.
Modern antivirus applications typically employ multiple detection methods to prevent an infection. Signature-based detection is the most common method. This involves scanning files for matches and keeping a database with distinct code fragments, also known as malware signatures. However, if attackers modify existing malicious code enough to be unable to be detected by these signatures, it's considered polymorphic and requires more advanced detection techniques.
A more sophisticated technique is heuristic-based detection. It attempts to detect malware by recognizing patterns that are specific to malicious code. For example, changing and deleting large quantities of data, altering settings for other programs, or connecting remotely to computers. Heuristic-based detection can cause security antivirussolutions.net/ alert fatigue and must be tuned carefully to be sure that false positives are not missed.
Look for a powerful antivirus program that is able to deal with polymorphic malware, ransomware memory attacks, and other advanced threats. It should also be simple to install on a wide variety of devices, including Macs and PCs, as well as work with various operating systems. It should not utilize too many system resources as this can cause a device to slow down or even crash.
