What is Avast?
Avast is a consumer security brand whose catalogue runs well past a single virus scanner. The site groups the range onto three shelves: device protection, covering Free Antivirus, Premium Security, the all-in-one Avast One and the Ultimate bundle; privacy tools including SecureLine VPN, AntiTrack, Secure Browser and BreachGuard; and performance utilities such as Cleanup Premium and Driver Updater.
The shared foundation across those tiers is a real-time scanning engine assembled from named modules: File Shield, Behavior Shield, Web Guard, Mail Shield and Smart Scan. Avast markets the free build as "multi-layered antivirus security," and the free-versus-premium table on the Premium Security page reserves AI scam detection, deepfake detection and email protection for its paid editions.
What the free tier actually includes
Avast Free Antivirus is unusually well equipped for a no-cost product. Alongside Smart Scan and the core shields, the free download page lists Network Inspector for spotting Wi-Fi weaknesses, Ransomware Shield, Quarantine, a Rescue Disk for booting a compromised machine, Hack Alerts for leaked credentials, and a firewall. Free Cleanup, free BreachGuard and a 60-day SecureLine VPN trial ride along. On a secondary laptop or a shared family PC, that adds up to a genuine security posture rather than a teaser.
Premium Security and the anti-scam layer
Paying moves Avast from malware defense into scam defense. Premium Security adds Email Guard and website scam detection, an advanced firewall, Remote Access Shield against brute-force attempts on exposed RDP, CyberCapture sandboxing for unknown files, webcam and password protection, secure file deletion, and automatic app updating. The comparison table on the product page marks AI-powered scam detection, deepfake video detection and fake-website identification as paid-only, with real-time threat blocking the single row checked for the free tier. Avast Assistant, the AI helper threaded through the suite, weighs suspicious messages and offers when you ask it to.
Coverage across every device in the house
Avast spans Windows, Mac, Android and iOS from one subscription, and the mobile builds are not stripped shells. Android gets Photo Vault for encrypted images, App Lock behind a PIN or fingerprint, Junk Cleaner, File Scanner, Wi-Fi Speed Test and Network Inspector. The iOS app carries Photo Vault plus password-leak monitoring for five email accounts. On Mac, Ransomware Shield, Wi-Fi security alerts, Do Not Disturb Mode and Network Inspector mirror much of the Windows set.
The Ultimate bundle for privacy and speed
Ultimate folds Premium Security together with SecureLine VPN, Cleanup Premium and AntiTrack under a single renewal. SecureLine VPN targets unsecured and public Wi-Fi, Cleanup Premium reclaims storage and tunes performance, and AntiTrack goes after the browser fingerprint that trails you between sites. Bought individually, those four products cost considerably more than the bundled subscription, which makes Ultimate the sensible pick for anyone who wanted a VPN anyway.
Independent lab results the vendor cites
Avast leans on third-party testing rather than benchmarks of its own making. The vendor reports an AV-Comparatives Top-Rated Product 2025 award and an AVLab Product of the Year 2026 award, a 95 percent phishing-page detection rate with no false alarms at AV-Comparatives, a full block of real-world threat samples at AV-Test, and a Total Accuracy Rating of 100 percent with zero false positives from SE Labs. Those figures sit on Avast marketing pages, so read them as vendor claims and check the lab reports directly if the numbers matter to your decision.
Who should choose Avast
Avast fits the household or sole trader who wants a strong free baseline now and a clear upgrade path later, once scam calls, phishing mail and a pile of shared devices become the actual threat. Premium Security is the right stop for most buyers, while Ultimate only earns its keep if the VPN and tuning tools get regular use.
It is a weaker fit for businesses that need centrally managed endpoints, policy enforcement and admin reporting, none of which these consumer plans offer, and for anyone allergic to promotional first-year pricing, since the introductory discount does not carry into renewal. Privacy-minded buyers should also read the current Avast privacy policy before installing.

Frequently asked questions
Is Avast good?
Yes, Avast is very good. In April 2026 AV-TEST awarded it a perfect 6/6 for protection, performance and usability, and AV-Comparatives measured a 99.97% malware block rate in March 2026. The free tier is genuinely strong. The main drawbacks are steep renewals and a past data-selling scandal, not detection quality.
How much is Avast?
Avast Free Antivirus costs $0. Premium Security is $49.08 for the first year on one device (renews $77.99) or $69.48 for up to 10 devices (renews $99.99). The Ultimate bundle, adding VPN, cleanup and AntiTrack, is $69.48 first year for 10 devices and renews at $139.99. Prices verified on avast.com in July 2026.
Is Avast safe to use?
Yes, Avast is safe today and its malware detection is top-tier. But from 2014 to 2020 its Jumpshot subsidiary sold users' browsing data to over 100 third parties; the FTC fined Avast $16.5 million in 2024 and banned the practice. The current product is clean, but that history is worth knowing before you buy.
Is Avast Free really free?
Yes. Avast Free Antivirus is free forever with no trial expiry, covering real-time malware, web and email protection on Windows, Mac, Android and iOS. It scored a perfect 6/6 at AV-TEST in April 2026. Expect frequent upsell prompts, and note that VPN, firewall and ransomware shield require a paid plan.
Avast vs Bitdefender: which is better?
Both score at or near perfect in independent labs. Bitdefender usually edges Avast on lightweight performance and features per dollar, and it carries no data-selling history. Avast counters with a stronger free tier and simpler interface. For value and a clean privacy record, Bitdefender leads; for a free option, Avast wins.
Verdict
Buy Avast if you want one of the strongest free antivirus engines available, or if the first-year Premium/Ultimate discount fits your budget — the lab scores are genuinely excellent (6/6 AV-TEST in April 2026, 99.97% AV-Comparatives in March 2026). Skip it if renewal prices matter (they jump to $77.99-$139.99), if you want a cheap bundled VPN, or if the 2024 FTC data-selling fine is a dealbreaker — Bitdefender delivers comparable protection with a cleaner privacy record.
