What Is Antivirus Software?

Antivirus software is a type of computer program designed to protect computers from malicious software, such as viruses, worms, and Trojan horses. It works by scanning the system for any suspicious activity or files that may be present on the computer. If it finds anything suspicious, it will alert the user and take action to remove or quarantine the threat. Antivirus programs can also detect spyware and other forms of malware that are not necessarily considered viruses but still pose a risk to your system’s security.

In addition to detecting threats, antivirus software can also help prevent them from entering your system in the first place by blocking certain websites or downloads known to contain malicious code. Some antivirus programs even offer real-time protection which scans all incoming data before allowing it onto your machine. This helps ensure that no new threats enter your system while you’re online or downloading files from unknown sources. By using an up-to-date antivirus program regularly, you can greatly reduce the chances of becoming infected with a virus or other form of malware on your computer.
