What is antivirus software?
Before diving into the subject matter, here is a short glimpse into what is meant by antivirus software. Also called anti-malware or AV software as the shortened form, antivirus software is a security program or set of programs that can scan your computer files and prevent and remove harmful viruses and malware from it. It was in 1971, the first ever reported case of computer virus appeared which was named the ‘Creeper virus’.
An American Computer Programmer named Ray Tomlinson developed a program that could eventually delete the Creeper virus and it was known as the “The Reaper”. According to some, The Reaper is the first ever antivirus software to be written but it was a virus that is specifically designed to destroy the Creeper virus. But by 1990 to 2000, there were great advancements in antivirus software and it led to the emergence of an antivirus software industry.
Antivirus software is installed on a computer to add to its security which can detect and fight various kinds of cyber attacks such as browser hijacking, Trojan horses, keyloggers, adware, worms, rootkits, and much more. Antivirus tools are necessary for any computer device as without its protection, the device can get affected by viruses and malware within minutes of connecting to the Internet.

How does antivirus software work?
Usually, antivirus software is run as background processes where either they scan the files and programs that enter your device and compare them with known viruses or scan the files already on your device and examine for any suspicious activity. Some of these antivirus programs also deliver real-time threat detection and conduct system scans to evaluate the security of your system. These softwares work frequently on the background of your computer and ensure no malware is detected and if found, prevent and inhibit its growth.
One of how this process is done is by comparing the existing files in your computer with a library that will have a malicious signature. This will help this software to identify possible threats and risks. Users are allowed to schedule scanning at definite times so that they can run automatically or they can also start new scans at any moment. Before scanning the system, the antivirus software will need privileged access to your entire system.
