Antivirus protection is software that detects and deflects malware that can penetrate a company’s digital systems to steal, misuse or corrupt data. It is compatible with many different devices that include laptops, desktops and mobile devices such as smartphones and tablets and even connected home gadgets such a smart TV or printer.
Modern antivirus solutions typically employ multiple detection methods to avoid an infection. Signature-based detection is an extremely popular method. This involves maintaining an array of distinct code fragments, also known as malware signatures, and scanning files to discover matches. If attackers modify malicious code to evade detection by signatures, they’re considered polymorphic, and require more sophisticated detection techniques.
A more advanced technique is heuristic-based detection. It tries to identify malware by recognizing patterns that are unique to malicious code. For instance, changing and deleting large amounts of data, changing settings for other applications, or remotely connecting to computers. Heuristic-based detection may cause security alert fatigue, and must be carefully crafted to be sure that false positives are not missed.
Find a virus protection program capable of handling the polymorphic nature of malware and ransomware. It should also be able deal with memory attacks, memory attacks, and other advanced threats. It should be simple to install on a range of devices, including Macs and Windows PCs. It should also be compatible with different operating systems. It shouldn’t use excessive system resources since this could cause a device to slow down or crash.
