Today’s online threats include much more than viruses. There are many different kinds of online threats that can infect your devices and give cybercriminals access to your personal data. You want protection against all of them. Norton AntiVirus is designed to help defend computers, smartphones or tablets against viruses and malware. Norton security technology includes multiple layers of defense to help catch and block all kinds of online threats that try to infect your devices.
How Antivirus Works
Antivirus scans and helps remove malware files that enter a computer, tablet or smartphone. Norton AntiVirus technology uses machine learning to determine if a file is good or bad, and can do so even if it’s the first time seeing that file.
Norton protection also uses “emulation” (running each file in a lightweight virtual machine) to cause online threats to reveal themselves – this happens in milliseconds as you double-click on files on your desktop. File signature data is now stored in the cloud, and Norton protection has undergone hundreds of optimizations on the antivirus engine to minimize impacting the user experience.
Norton security technology includes multiple defenses against viruses and malware. Our technology is powered by artificial intelligence (AI) and machine learning, and we are part of one of the world’s largest civilian cyber intelligence networks. Our protection includes:
Intrusion Prevention System (IPS)
Analyzes information arriving from a network (like the Internet) and helps block potential online threats before they hit your computer.
AntiVirus with Advanced Machine Learning
Scans and helps remove malware files that enter a device, using emulation to test and see what files do, and machine learning.
Reputation Protection (Insight)
Uses the reputation information gathered from Symantec’s Global Intelligence Network to classify software application files on their attributes.
Behavioral Protection (SONAR)
Uses artificial intelligence to classify applications based on behavior, and automatically helps block applications that display suspicious behavior.
Proactive Exploit Protection (PEP)
Helps protect against ‘zero-day’ attacks that exploit vulnerabilities in applications or the operating system.
Helps detect and lets you remove high-risk applications and malware that may be residing on your computer.
