Antivirus vs Internet Security: What's the Difference?
Published January 18, 2026 · 5 min read
The short answer
Antivirus software is focused on detecting and removing malware on the device it's installed on. Internet Security software includes that same malware scanning, plus network- and browser-facing protections — most commonly a managed firewall and phishing/malicious-site filtering.
Why this distinction matters when shopping
The exact feature line that separates the two tiers differs by manufacturer, so the names alone aren't a reliable comparison tool. Compare the actual feature list for each plan, which our product overviews summarize and the publisher's website confirms, rather than relying on the tier name.
As a general rule: if you mainly want malware scanning on a single, well-maintained device, plain antivirus is usually enough. If you do a lot of online banking or shopping, or want more control over network-level protection, Internet Security is the more common step up.
Neither tier typically includes a VPN or backup
Those extras usually appear at the 'Total Security' or '360' tier instead. See our Total Security category page for products that bundle those features in.
