Antivirus Software Guide

Antivirus software shields your PC from malware-related infections. This includes viruses, Trojans, spyware, rootkits and adware as well as worms. It can also detect and repair any damage caused by these threats.

Antivirus software is an essential tool to protect any device, including a mobile or computer. They are able to detect and eliminate ransomware, phishing emails spam, and other malicious software. They are also able to scan and protect connected appliances, such as printers and SmartTVs.

When selecting an antivirus software be sure to choose one that has an extensive history of passing numerous tests and receiving positive reviews from independent laboratories. Organisations like Virus Bulletin, TechRadar, NSS Labs and AV Comparatives conduct tests and provide detailed reviews of the various antivirus software options. They will explain what protections they offer and how well the program performs, and if it’s worth the money.

Traditional antivirus software rely on the signature, or binary pattern of a virus to determine if it is. However, hackers have kept up with this by creating polymorphic and oligomorphic viruses which encrypt portions of themselves or modify their appearance to not match signatures of viruses stored in databases of antivirus. The latest antivirus programs are designed to be more effective against these advanced malware threats using sandbox analysis, which executes the file in a virtual environment to examine the way it behaves prior to allowing it to enter the system.
