Scan your Wi-Fi network for security threats
Avast Mobile Security enables you to scan a Wi-Fi network for problems with the router, encryption, Wi-Fi, and connection. After installation, Wi-Fi Security runs automatically in the background and notifies you if anything is wrong. To disable this automatic notification, go to Settings and tap the slider next to Notify me about Wi-Fi threats so that it changes from green to white.
To manually rescan a Wi-Fi network:
- Tap the Wi-Fi Security panel on the Protection screen.
- Tap Rescan.
- When the scan is complete, Wi-Fi Security reports any issues found and prompts you to resolve them. If no issues are found, a status message is displayed in green.
Activate Secure Browsing
Secure Browsing uses Avast's VPN (Virtual Private Network) infrastructure to create a secured VPN connection. This protects the data you upload and download from the internet, secures data sent from your device, and keeps your internet activity completely private. Secure Browsing is only available in the paid Pro version of Avast Mobile Security for iOS.
The first time you activate Secure Browsing, the app will prompt you to install a VPN profile:
- Tap the Secure Browsing panel on the Protection screen.
- Tap Activate Secure Browsing.
- Read the Logging Policy And Use, then tap Accept.
- Tap Install Profile.
- When prompted, tap Allow and enter your passcode, touch or face ID. Your VPN profile is installed and Secure Browsing is automatically activated, connecting you to the closest server we have in your location.
- The protection screen confirms You are safe and VPN is displayed at the top of your screen indicating that you are currently connected to a secure VPN.
To deactivate Secure Browsing, tap the slider on the Secure Browsing panel so that it changes from green (Connection is encrypted) to white (Not active).
Passcode protect your photos
Photo Vault allows you to protect access to your photos with a passcode. After moving photos to the vault, they are encrypted and hidden.

- Tap Set Passcode.
- Enter a 4-digit passcode, then enter your passcode again to confirm it.
Your passcode is set. Next time you want to access Photo Vault, you will be prompted to enter your passcode to gain access to the vault. If your device has touch or face ID capability, you will have the option to enable this functionality after you have set up a passcode. If you choose to enable touch or face ID, this will replace your passcode for accessing Photo Vault.
Add photos or images to Photo Vault
You can add existing photos or images to your Photo Vault from the Photo Library on your device, or you can use the camera on your device to take a photo and import it directly into your Photo Vault.
To add photos or images to Photo Vault:

+button in the top-left corner.
