Avast’s US store lists Free Antivirus, Premium Security, and Ultimate; Avast One is presented separately as an app combining antivirus, scam protection, and privacy tools. Feature descriptions below reflect Avast’s own product pages, not independent tests of effectiveness.
Which Avast option fits your needs?
| Option | What Avast says it includes | What to check |
|---|---|---|
| Free Antivirus | Avast offers it as a free download. Its Windows 11 page promotes free real-time antivirus protection. | Confirm that the version supports your operating system; do not assume paid features are included. |
| Premium Security | Avast promotes advanced antivirus, email and online scam protection, mobile SMS scam protection, and privacy-related features. | Choose by platform and device count before comparing offers. The US page presents several coverage options. |
| Avast One | Avast describes it as a single app combining antivirus, scam protection, and privacy tools, with free and premium options. | Check the tier and availability in your country; details can vary by region. |
| Ultimate | Avast says the subscription includes Premium Security, SecureLine VPN, Cleanup Premium, and AntiTrack. | Consider whether you will use the VPN, cleanup, and anti-tracking services rather than judging the bundle by its number of features. |
See Avast’s US store, Avast One overview, Premium Security page, and Ultimate page for the vendor’s current descriptions. These pages establish what Avast advertises, not independently verified protection or performance.

Is Avast antivirus free?
Yes. Avast’s US store offers Free Antivirus as a free download, and its Windows 11 page advertises free real-time antivirus protection. The free option is a starting point if you want antivirus without a paid subscription; it should not be treated as equivalent to every feature in a paid plan. Check the product page for your operating system and region before downloading.
Recommended Free Tools
Avast also describes free and premium versions of Avast One. That product is framed as a unified app with antivirus, scam protection, and privacy tools; confirm which features apply to the tier available where you live.

What does Avast Premium Security add?
Avast’s Premium Security page promotes additional protections beyond its free offering, including email and online scam protection, mobile SMS scam protection, and privacy-related features. The precise feature set and supported devices depend on the selected offer, platform, and country. Review the live plan details rather than assuming every advertised feature applies to every device.
Device coverage matters as much as the feature list
The US Premium Security page presents single-device or device-pair choices and a 10-device option. Those labels do not by themselves settle whether a particular plan covers the mix of computers and phones you own. Check the operating systems listed for the exact offer and count the devices you intend to protect before checkout.

Does Avast protect against ransomware?
Avast advertises ransomware protection on its Windows 11 page. That is a vendor feature claim, not an independent measurement of how well the product blocks ransomware in real-world conditions. Avast’s EU comparison page also names ransomware protection and an advanced firewall among feature distinctions, but availability should not be assumed across all plans, platforms, or regions. Confirm the live comparison and plan terms for your location.

Is Avast Ultimate worth choosing?
Ultimate is a bundle rather than simply a larger device allowance: Avast says it combines Premium Security with SecureLine VPN, Cleanup Premium, and AntiTrack. It may suit someone who wants those services together, but extra bundled tools are not automatically useful. Compare the exact subscription terms with the protections and services you will actually use; if you only want antivirus, a simpler option may fit better.

Prices are time-sensitive and region-specific. On October 7, 2026, Avast’s US store showed discounted first-year offers alongside higher renewal-price references; the separate Premium Security page showed a different offer presentation. These snapshots should not be combined or treated as guaranteed checkout prices. Verify the current amount, renewal terms, selected device count, and country directly on the offer before subscribing.
