Avast Premium Security Review 2026
Avast is the most widely installed antivirus software in the world — largely because its free tier is genuinely functional. Avast Free Antivirus provides real-time malware scanning, a Wi-Fi network inspector, and browser protection at no cost.
Avast Premium Security builds on this foundation with privacy-focused extras: webcam shielding, sandboxed execution, and ransomware protection. Whether the upgrade is worth it depends heavily on your threat model — and your willingness to overlook Avast’s troubled privacy history.
Free vs Premium
Avast Free includes:
- Real-time malware scanning
- Browser extension with phishing protection
- Wi-Fi Inspector (scan for network vulnerabilities)
- Basic ransomware protection
Avast Premium Security adds:
- Webcam Shield (prevents unauthorized camera access)
- Sandbox (run unknown files in isolation)
- Real Site (DNS hijacking protection)
- Enhanced ransomware protection
- Software Updater (auto-patches vulnerable software)
For most home users, the free tier covers the basics. The premium upgrade is most justified for users who handle sensitive work from a webcam-equipped laptop or regularly receive unknown files.
Wi-Fi Inspector
Avast’s Wi-Fi Inspector scans your local network for devices with weak passwords, outdated firmware, open ports, or known vulnerabilities. It’s one of the better free network audit tools available to consumers — comparable to what you’d normally need a separate scanner (like Shodan or Nmap) to achieve.
This feature is available on both the free and premium tiers, making it a legitimate reason to choose Avast even as a free user.
Webcam Shield
Webcam Shield blocks all unauthorized applications from accessing your device camera. You define a trusted list; anything else gets blocked with a notification. In practice, this means malware-based RATs (remote access trojans) cannot silently activate your webcam even if they bypass other protection layers.
This feature is unique to Avast (and its sister product AVG) in the mainstream antivirus market.
The Privacy Question
In 2020, it was revealed that Avast’s subsidiary Jumpshot was selling detailed browsing data collected from Avast users — including free users — to advertising and analytics firms. Avast subsequently shut down Jumpshot and updated its data collection policies.
The company (now part of Gen Digital, which also owns Norton, NortonLifeLock, and AVG) has made commitments to transparency since then. However, users who prioritize privacy — particularly those who chose Avast specifically to protect their data — should be aware of this history and review current data practices before committing.
Detection Performance
In recent AV-TEST evaluations, Avast Premium Security achieves 98.5% detection — solid, but below Norton (99.9%+) and Bitdefender (100%). The gap is small in real-world terms but measurable in lab conditions.
Pricing
- 1 device: ~$35.88/year ($2.99/mo)
- 10 devices: ~$49.99/year — strong multi-device value
- Free plan: Avast Free Antivirus (always available)
The 10-device plan is notably competitive — protecting an entire household’s devices for under $50/year.
Verdict
Avast Premium Security is a capable antivirus with a genuine free tier and some unique features (Webcam Shield, Wi-Fi Inspector). The data-selling history is a legitimate concern for privacy-focused users. For those who prioritize privacy, Bitdefender or Malwarebytes are cleaner choices.
