Antivirus Software Guide

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

Antivirus software is an essential tool in protecting any computer and mobile device. They are able to detect and eliminate ransomware, phishing messages, spam, and other malicious software. They can even scan and protect connected devices like printers, SmartTVs, cameras, and other appliances from malware infections as well.

When selecting an antivirus software make sure you choose one with a long history of being able to pass multiple tests and obtaining positive reviews from independent labs. Organizations such as Virus Bulletin, TechRadar, NSS Labs and AV-Comparatives conduct tests and provide thorough reviews of the various antivirus software options. They will tell you what security features they provide, how well the program performs, and if it is worth your money.

Traditional antivirus software rely on the signature or binary pattern of viruses, to identify it. However hackers have kept pace with this, by creating oligomorphic and polymorphic viruses, that encrypt their own parts or modify their appearance to not match virus signatures stored in antivirus databases. Sandbox analysis is employed by newer antivirus programs to combat these sophisticated malware threats. The program runs the file within the virtual environment to see how it behaves.
