Most people trying to protect themselves online end up with the same problem: an antivirus on the laptop, a VPN subscription somewhere else, a disk cleaner they downloaded two years ago, and nothing at all on their phone. Avast just launched a new version of Avast One that tries to fix this by putting everything under one roof.
A catalog that finally makes sense
Avast has not exactly made things easy for its users in recent years. Between Avast Free Antivirus, the older Avast One, Avast Premium Security, and assorted mobile offerings, it was genuinely hard to know what you were buying or whether you already had it. The company, which is part of Gen Digital alongside Norton, AVG, and Avira, has now reorganized its consumer offering around a single modular application available on Windows, macOS, Android, and iOS.
The logic is straightforward: you start with a free base that includes real, functional protection, and you add modules from inside the same app if and when you need them. No separate downloads, no new accounts, no re-entering payment details. Everything runs from one dashboard.
That distinction matters more than it sounds. The old model, which most security software still follows, forces users to choose between a stripped-down free product and a full paid bundle that includes features they will never touch. Avast One is trying to thread a different needle: free protection that is actually good, with paid add-ons that are genuinely optional.
What the free version actually covers
The free tier is not a teaser: It includes Avast’s real-time antivirus engine which covers malware detection, ransomware blocking, and malicious download prevention. It also includes Scam Guardian, an anti-scam module that analyzes web pages in real time to catch phishing sites and fraudulent storefronts before you interact with them. There is also an Avast Assistant which is an AI-powered tool built directly into the app and it can answer questions about suspicious links or messages on the spot.
There is also a module called AI Agent Protection, which targets a newer category of threat: AI tools that act on behalf of users such as assistants that can read files or send emails, can be hijacked through injected instructions. This module monitors those workflows and flags anything that looks tampered with.
The free version requires no credit card and no time limit. It stays free.
The modular layer on top
Inside the app’s sidebar, additional modules are visible and clearly marked as paid. Users can activate any of them independently without leaving the application or starting a new setup from scratch. The modules that can be added include the following:
- SecureLine VPN, after the 60-days trial period ends, is available as a standalone subscription. The recommended plan runs $3.89 per month billed over two years, covering up to 10 devices simultaneously across PC, Mac, Android, and iOS.
- Cleanup Premium goes beyond the free scan to handle performance issues, unused apps, startup programs, duplicate files, and browser clutter. The recommended two-year plan comes to $2.89 per month.
- BreachGuard monitors the dark web for exposed personal data tied to your email addresses, sends real-time alerts if something leaks, and walks you through the steps to contain the damage. The recommended plan is $2.39 per month on a two-year subscription.
For users who want more scam protection than the free tier provides, Premium Security adds coverage for scam calls, fraudulent SMS messages, suspicious emails, and unsafe Wi-Fi networks – and it also includes remote access attack protection. That plan starts at $49.99 for the first year and covers one Mac and one mobile device. The Avast Ultimate tier adds SecureLine VPN, Cleanup Premium, and AntiTrack on top of everything in Premium Security, also at $49.99 for the first year.
The key selling point of the modular approach is that none of these are bundled together by default: Someone who only wants dark web monitoring pays for BreachGuard. Someone who just needs a VPN for travel pays for SecureLine. The app makes it easy to see what is active, what is available, and what each module does before committing to anything.
What Avast One is and is not
It is worth being clear about one thing: Avast One is not the same product as Avast Free Antivirus, even though both are free to start. Avast Free Antivirus is a standalone antivirus with no modular layer and no path to add privacy or performance tools without switching products – and Avast One is a platform. The antivirus is the foundation, and everything else, VPN, breach monitoring, cleanup, scam call protection, can be layered on top of it from inside the same interface. The two products now exist side by side, but Avast One is clearly where the company is putting its development resources.
Avast One is a reasonable answer to a real problem: Managing three or four separate security subscriptions across two devices is a hassle most people quietly put up with, and the all-in-one suites that already exist tend to charge for the entire package whether you use it all or not. A modular system that lets users build up from a solid free base is a more honest approach to how people actually think about this stuff.
