Protect your PC

Avast One includes many protection features, such as scans and shields, which help your PC run safely and alert you about harmful files and connections. To use these features and manage their settings:

  1. Click the Device protection tile on the Avast One dashboard.
  2. Select one of the following features:
    • Scans: Run Deep Virus Scan, Targeted Scan, Boot Time Scan, and Disk Clean.
    • Real-time file scanning: Manage settings for Real-time file scanning, which scans each file as you open it.
    • Ransomware shield: Protect specific folders and file types from being corrupted by ransomware. From here, you can also block or allow specific apps that try to access your protected folders and file types.
    • Web Shield: Manage settings for Web Shield, which blocks web attacks and unsafe downloads. From here, you can also click Show Blocked websites to add a website that you want to block.
    • Firewall: Define which programs and services on your PC can connect to the internet, and how. Select Block next to a service you don't want to connect to the internet. From here, you can also specify whether you want your PC to be visible or hidden. We recommend keeping your PC hidden unless you want to connect to another device on a private network.
    • Virus Vault: Add files to the Virus Vault, which acts as a quarantine for suspicious files. From here, you can send them to Avast Threat Labs for analysis, restore the files, and add the files as exceptions.
    • Sensitive Data Shield: Protect files containing sensitive personal data, such as passwords and banking information, from unauthorized access and malware.
    • Fraudulent site detection: Secure your URLs, and prevent hackers from redirecting you to fake websites by hijacking your DNS (Domain Name System) settings.

Browse privately

Avast One includes a Virtual Private Network (VPN) feature, called Secure connection, which disguises your real IP address while you browse online. To connect to the VPN:

  1. Click the Secure connection tile on the Avast One Dashboard.
  2. Click the slider so that it changes from orange (OFF) to green (ON).
  3. Additionally, allow the VPN to connect automatically by ticking the box next to Turn on VPN automatically.

Protect your identity

Avast One's built-in identity protection features protect your personal data and alert you if a breach occurs. To use these features and manage their settings:

  1. Click the Personal identity tile on the Avast One Dashboard.
  2. Select one of the following features:
    • Data leak monitoring: monitors your email addresses for leaks, and alerts you if any breaches occur.
    • Browser clean-up: deletes browser history and cache that track you as you browse online.
    • Webcam Shield: blocks applications and websites from accessing your webcam without your permission.

Boost performance

When you use the performance tools regularly, they can enhance your PC's performance, clear disk space, and eliminate unwanted programs and security risks. To use the performance features:

  1. Click the Smooth performance tile on the Avast One dashboard.
  2. Select one of the following features:
