How Antivirus Works

How do antivirus apps and antivirus software work?

Antivirus scans and helps remove viruses and malware files that may infect a computer, tablet, or smartphone. Norton AntiVirus technology employs machine learning to assess whether a file is safe or harmful, even if it’s encountered for the first time.

Norton protection also utilizes "emulation" by running each file in a lightweight virtual machine, allowing online threats to reveal themselves in mere milliseconds as you double-click files on your desktop. File signature data is now stored in the cloud, and Norton protection has undergone numerous optimizations to the antivirus engine to minimize its impact on user experience.

Antivirus for Windows®

Antivirus software for Windows computers


Norton was one of the first antivirus solutions for Windows computers, and we have been innovating for decades to discover new methods of protecting PCs.

Today, the antivirus protection in Norton solutions employs advanced machine learning and emulation to assess whether files are safe or harmful.

Additionally, Norton device security offers various other methods to safeguard your computer beyond just antivirus protection.

Protection for PCs starts at the network-level, with Intrusion Prevention working together with the Smart Firewall to analyze network traffic and help block potential online threats before they get on your computer.

Antivirus for Mac®

The belief that Mac computers are immune to viruses and malware is simply a myth.

Mac computers can indeed be affected by viruses and require file-based antivirus protection. Furthermore, they benefit from additional layers of security found in a comprehensive device security software suite, including a firewall, intrusion prevention, and anti-phishing protection.

We have been protecting Mac computers for decades. Today, our advanced security measures and 24/7 global threat monitoring work to outsmart cybercriminals and prevent the latest attacks from reaching your Mac.
