Avast is one of the most widely used antivirus brands in the world, largely because its free tier is genuinely good — strong malware detection at no cost, on hundreds of millions of devices. In 2026 the paid Avast One suites add a VPN, tune-up tools, and identity features. Verdict: Avast’s free antivirus is one of the best free options available and its protection is well-tested — but the brand carries a real trust asterisk from a past data-selling scandal, and the paid experience is heavy on upsell pop-ups. Use the free tier with clear eyes, and weigh the history before paying.
Avast’s story is a mix of genuine technical strength and a reputation it is still repairing. Here is the honest read.
Company overview
Avast is a security brand founded in Prague, Czech Republic, in 1988, and it remains a well-known European name in consumer antivirus. Since 2022 it has been owned by Gen Digital — the same US-based, publicly traded parent that owns Norton, AVG, Avira, and LifeLock — formed when Avast merged with NortonLifeLock. That means Avast and AVG now share much of the same underlying engine and sit alongside Norton in one portfolio.
Avast’s reputation is genuinely divided. On protection, it is well regarded and scores well at independent labs. But the brand took a serious reputational hit in 2019–2020 when it was revealed that a subsidiary, Jumpshot, had been collecting and selling detailed user browsing data. Avast shut Jumpshot down after the reporting, and in 2024 the US FTC ordered Avast to pay a settlement and barred it from selling browsing data for advertising. This history is the single most important thing to understand about the brand, and it competes with Bitdefender, ESET, Norton, and Microsoft Defender — the full field is in our Best Antivirus Software 2026 for Windows and Mac guide.
What Avast makes
Avast’s consumer line centers on its free antivirus and the Avast One platform:
- Avast Free Antivirus — the flagship free tier: real-time malware protection, a basic web shield, and Wi-Fi scanning at no cost.
- Avast One — the modern all-in-one paid platform combining antivirus, a VPN, tune-up/cleanup tools, and privacy/identity features, in Essential (free), Individual, and Family tiers.
- Avast Premium Security — the traditional paid antivirus suite with advanced firewall, ransomware shield, and anti-scam tools.
- Standalone tools — Avast SecureLine VPN, Avast Cleanup, and Avast AntiTrack.
- Mobile apps for Android and iOS.
Standout Avast products in 2026
Avast Free Antivirus. The reason the brand is so widespread: genuinely capable free real-time protection that consistently scores well in independent tests. A regular mention in our Best Antivirus Software 2026 for Windows and Mac guide.
Avast One. The flagship paid platform, bundling antivirus, VPN, and privacy tools in one dashboard — Avast’s answer to Norton 360, aimed at buyers who want everything in a single subscription.
Avast SecureLine VPN. A competent bundled VPN for casual use, though it trails dedicated providers on features and server breadth in our Best VPN Services 2026: Which One Wins for US & UK? guide.
Avast Cleanup Premium. A system tune-up tool — useful but the kind of extra that also drives some of Avast’s persistent upsell prompts.
For most buyers, the free tier is the standout; those who want the full bundle should look at Avast One.
Strengths
One of the best free antivirus tiers. Avast Free Antivirus offers strong, real-time malware protection at no cost — a genuinely useful product used by hundreds of millions.
Good independent-lab scores. Avast’s detection engine performs well at AV-TEST and AV-Comparatives, with effective anti-phishing and ransomware protection.
A polished, friendly interface. Avast One in particular has a clean, approachable dashboard that beginners find easy to navigate.
A broad all-in-one bundle. Avast One pulls antivirus, VPN, and privacy tools together for buyers who want a single subscription.
Wide platform support and huge threat network. A vast install base gives Avast broad real-world threat visibility across Windows, macOS, Android, and iOS.
Weaknesses & criticisms
A serious data-privacy scandal in its past. The Jumpshot browsing-data collection and sale — and the resulting 2024 FTC settlement and ban on selling browsing data — is a genuine trust issue. Avast has changed course, but the history is a fair reason for caution.
Heavy upsell pop-ups. The free tier in particular pushes frequent notifications nudging you toward paid upgrades and add-ons, which many users find intrusive.
Overlap and cross-selling with the Gen Digital family. Avast, AVG, and Norton now share ownership and engine tech, and the group’s cross-sell culture is a common complaint.
Bundled extras are competent, not class-leading. The VPN and cleanup tools are convenient but do not beat dedicated alternatives.
Renewal pricing to watch. As across the category, cheap first-year pricing gives way to higher standard renewals.
Reliability & support
On core protection, Avast is reliable: detection is strong, updates are automatic and frequent, and the apps are stable across platforms. The free tier is dependable day to day, and Avast One is a stable, well-built suite. The reliability concerns are less about whether it stops malware and more about trust and noise — the privacy history and the volume of upsell prompts.
Support is tiered: free users lean on a large knowledge base and community forums, while paid customers get access to email and chat/phone support. Avast typically offers a 30-day money-back guarantee on paid plans. The key ownership-cost caveats are behavioral and reputational: budget for the renewal step-up, turn off unwanted notifications, and go in aware of the data-selling history.

Who should buy Avast
Buy Avast — specifically the free tier — if you want genuinely capable no-cost malware protection and are comfortable managing the upsell prompts. Avast One suits buyers who want a friendly, all-in-one paid bundle with a polished interface and do not mind that the extras are convenient rather than best-in-class.
Look elsewhere if the data-privacy history is a dealbreaker for you — a completely understandable position — in which case ESET (European, privately owned, strong privacy record) or Bitdefender are better-trusted picks. If you want the lightest footprint, ESET wins; if you want a deep identity-protection bundle, Norton’s LifeLock tie-in is stronger. The full field is ranked in Best Antivirus Software 2026 for Windows and Mac.
FAQ
Is Avast a good brand?
Yes on protection — its free antivirus is one of the best free options and its paid suites are capable and well-tested. But the brand carries a real trust asterisk from the Jumpshot data-selling scandal and the resulting FTC action, plus a naggy, upsell-heavy experience. Good product, checkered history.
Is Avast reliable?
Yes on the core job: detection is strong, updates are automatic, and the apps are stable across platforms. The reliability concerns are about trust and noise — the past data-privacy issue and the volume of upsell prompts — rather than whether it stops malware.
Where is Avast from and who owns it?
Avast was founded in Prague, Czech Republic, in 1988. Since 2022 it has been owned by Gen Digital, the US-based, publicly traded parent that also owns Norton, AVG, Avira, and LifeLock, formed when Avast merged with NortonLifeLock.
Is Avast safe to use?
Its protection is trusted and independently tested. The important caveat is the 2019–2020 Jumpshot scandal, in which an Avast subsidiary collected and sold browsing data; the unit was shut down and the FTC ordered a settlement and a ban on selling browsing data in 2024. The malware protection itself is safe and effective, but weigh the privacy history.
What was the Avast data-selling scandal?
A former Avast subsidiary, Jumpshot, collected detailed user browsing data and sold it to third parties. After investigative reporting in 2019–2020, Avast shut Jumpshot down, and in 2024 the US FTC ordered Avast to pay a settlement and barred it from selling browsing data for advertising.
Avast or AVG — which is better?
They are effectively siblings: both are now owned by Gen Digital and share much of the same underlying engine, so protection is very similar. The choice comes down to interface preference and pricing rather than a meaningful difference in security.
