Antivirus protection software blocks malware that could penetrate the electronic systems of a company to steal, misuse or damage data. It can be used on many devices such as laptops, desktops, and mobile devices such as smartphones and tablets, as well as connected home gadgets such a smart TV and printers.
Modern antivirus solutions employ multiple detection methods to block the spread of a single virus. A common method is detection based on signatures. This involves analyzing files for matches and keeping an inventory of distinct code fragments, also known as malware signatures. If hackers modify malicious code in order to avoid detection by signatures, they’re deemed polymorphic and require more sophisticated detection methods.
A more advanced technique is heuristic-based detection. It tries to detect malware by recognizing patterns that are unique to malicious code, like altering and deleting large amounts of data, changing the settings of other programs or remotely connecting to computers. Security detection using algorithms can lead to false positives and fatigue.
Look for a powerful antivirus program that is able to handle ransomware, polymorphic malware memory attacks, and other advanced threats. It should also be simple to install on a wide range of devices, which includes Macs and PCs, and also work with different operating systems. It should not utilize too many system resources as this can cause the device to slow down or crash.
