Antivirus protection software detects and deflects malware that could infiltrate enterprise’s digital systems in order to steal, alter or corrupt data. It can be installed on a wide range of devices including laptops, desktops and mobile devices such as smartphones and tablets and also on connected home appliances like smart TV and printers.
Modern antivirus software typically employs multiple detection methods to avoid the spread of a single infection. One common method is detection based on signatures. This involves maintaining an array of distinct code fragments, also known as malware signatures, and then scanning files to identify matches. If hackers modify malicious code in order to avoid detection by signatures, they are deemed polymorphic and require more sophisticated detection techniques.
A more advanced method is heuristic-based detection. It tries to detect malware by recognizing patterns that are specific to malware, such as editing and deleting large quantities of data, altering the settings of other programs or remotely connecting to computers. The use of algorithms for detection can cause security alert fatigue, and must be carefully crafted to be sure that false positives are not missed.
Find a virus protection program that can handle polymorphic malware and ransomware. It should also be able deal with memory attacks, memory attacks and other advanced threats. It should also be simple to install on a wide variety of devices, including Macs and PCs, and run on various operating systems. In addition, it should not consume too many system resources, since this could hinder the performance of a particular device, or lead to computer crashes.
