Antivirus protection software detects and blocks malware that can penetrate corporate systems to take, misuse or damage data. It can be utilized on various devices including laptops, desktops and mobile devices such as tablets and smartphones as well as connected home gadgets such a smart TV or printer.
Modern antivirus solutions typically employ multiple detection techniques to prevent the spread of a single infection. Signature-based detection is the most common method. This involves scanning files for matches and maintaining a database that contains distinct code fragments, also known as malware signatures. If hackers modify malicious code to avoid recognition by signatures, they’re considered polymorphic and need more advanced detection methods.
Heuristic-based detection is an advanced method. It tries to detect malware by identifying patterns that are unique to malicious code, for example, modifying and deleting large amounts of data, changing the settings of other programs or remotely connecting to computers. Heuristic-based detection can cause security alert fatigue http://www.antivirussolutions.net/windows-defender-vs-avast-which-one-is-more-secure/ and must be carefully crafted to be sure that false positives are not missed.
Choose a strong virus protection program that can handle polymorphic malware, ransomware memory attacks, and other advanced threats. It should also be easy to deploy across a wide range of devices, including Macs and PCs, as well as work with various operating systems. Lastly, it should not consume too many system resources, since this could slow down the performance of a particular device or cause computer crashes.
