Antivirus protection is software that detects and blocks malware that could infiltrate company’s digital systems to steal, alter or corrupt data. It can be installed on many devices including laptops, desktops and mobile devices, such as tablets and smartphones and even connected home devices such as smart TV or printer.
Modern antivirus applications employ multiple detection techniques to prevent one virus. One method that is commonly used is a signature-based detection. This involves scanning files for matches and keeping a database with distinct code fragments, also known as malware signatures. If attackers modify malicious code to avoid recognition by signatures, they’re deemed polymorphic and require more advanced detection methods.
A more advanced technique is heuristic-based detection. It tries to identify malware by recognizing patterns that are specific to malicious software. Examples include modifying and deleting large amounts of data, altering settings for other software, or remote connections with computers. Heuristic-based detection can cause anxiety about security alerts and needs to be carefully tuned to be sure that false positives are not missed.
Choose a strong antivirus program that is able to handle ransomware, polymorphic malware, memory attacks antivirussolutions.net/windows-defender-vs-avast-which-one-is-more-secure/ and other advanced threats. It should also be simple to install across a broad range of devices, including Macs and PCs, and also work with different operating systems. It should not consume excessive system resources, as this can cause a device to slow down or crash.
