Antivirus protection software detects and blocks malware that could infiltrate the digital systems of a business to steal, misuse or destroy data. It can be used to protect a range of devices, including desktops, laptops mobile devices such as tablets and smartphones as well as connected home devices like printers and smart TVs.
Modern antivirus solutions typically employ multiple detection techniques to prevent one infection. Signature-based detection is a common method. This involves scanning files for matches and maintaining a database that contains distinct code snippets known as malware signatures. However, if hackers alter existing malicious code enough to not be recognized by these signatures, it's considered polymorphic and requires sophisticated detection methods.
A more advanced technique is heuristic-based detection. It tries to identify malware by recognizing patterns that are specific to malicious software. For example, changing and deleting large quantities of data, changing settings for other applications, or remotely connecting with computers. Heuristic-based detection may cause anxiety about security alerts and needs to be carefully calibrated to prevent false positives.
Search for a security program that can handle polymorphic malware and ransomware. It should also be able manage memory attacks, memory attacks, and other advanced threats. It should be simple to install on a variety of devices including Macs and Windows PCs. It should also operate on various operating systems. Additionally, it shouldn't consume too many system resources, as this can hinder the performance of an individual device, and even cause computer crashes.
