Antivirus Software Guide

Antivirus software is one type of software that guards computers from malware infection. This includes viruses and Trojans as well as spyware, adware rootkits and worms. It can also detect and repair any damage caused by these threats.

Antivirus software is an essential component for any laptop or device. They can identify and remove ransomware, phishing emails spam, and other dangerous software. They can also protect and scan connected appliances like printers and SmartTVs.

When choosing an antivirus program make sure you choose one that has been tested and has received positive reviews from independent laboratories. Organizations like Virus Bulletin, TechRadar, NSS Labs and AV-Comparatives conduct tests and provide comprehensive reviews of various antivirus software choices. They will explain what security features they provide, how well the program performs, and if it’s worth the money.

While traditional antivirus software relies on the signature, or binary pattern, of a virus to identify it as a threat, hackers have managed to stay ahead of this by creating oligomorphic, polymorphic, and recently metamorphic viruses, which encrypt certain parts of themselves or otherwise modify their appearance to match the signatures of viruses in antivirus databases. Sandbox analysis is used by the latest antivirus programs to tackle these sophisticated malware threats. The program executes the file in the virtual environment to observe how it behaves.
