Antivirus software, or anti-virus software, also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses.

Antivirus software is a program or set of programs that are designed to prevent, search for, detect, and remove software viruses, and other malicious software like worms, trojans, adware, and more.

Why Do I Need Antivirus Software?

These tools are critical for users to have installed and up-to-date because a computer without antivirus software protection will be infected within minutes of connecting to the internet. The bombardment is constant, which means antivirus companies have to update their detection tools regularly to deal with the more than 60,000 new pieces of malware created daily.

Today’s malware (an umbrella term that encompasses computer viruses) changes appearance quickly to avoid detection by older, definition-based antivirus software. Viruses can be programmed to cause damage to your device, prevent a user from accessing data, or to take control of your computer.
