How does anti-virus software work?
Anti-virus software is designed to detect, prevent, and take action to remove malicious software, also known as malware. There are three primary ways that anti-virus software works:
Prevention: Anti-virus software uses known characteristics of malware to block it from running or infecting your computer. This is done either by identifying and removing infected files or by stopping malicious processes before they start.
Detection: If prevention methods fail and malware manages to get on your system, anti-virus software can detect it by scanning your computer for malware signatures. A malware signature is a piece of code that is unique to a specific type of malware. Once a piece of malware is discovered, its signature is added to the anti-virus software’s database so that it can be detected in the future.
Removal: If anti-virus software detects malware, it will take action to remove it from your computer. This may involve quarantining the malware, which isolates it from the rest of your system, or deleting it completely.
Anti-virus software is an important tool in the fight against malware. It can prevent infection in the first place, and if malware does get on your system, it can help remove it.

What is the difference between anti-virus software and a firewall?
When your computer is connected to the internet, it is vulnerable to attacks from viruses, worms, and other malicious software, which can damage your files, steal your personal information, or give attackers control of your computer. Anti-virus software helps protect your computer against these threats by identifying and removing malicious software.
A firewall is a system that helps protect your computer from unauthorized access by blocking incoming and outgoing connections that are not authorized. Firewalls can be hardware devices, software programs, or a combination of both.
