Core Shields

The following shields are available in Avast Security:

  • File Shield: scans applications, programs, and files saved on your Mac for malicious threats in real-time before allowing them to be opened, run, modified, or saved. If malware is detected, File Shield prevents the program or file from infecting your Mac.
  • Web Shield: scans data that is transferred when you browse the internet in real-time. This prevents malware, such as malicious scripts, from being downloaded and run on your Mac.
  • Email Shield: scans email attachments in real-time before allowing them to be opened, run, modified, or saved. If malware is detected, Email Shield prevents the program or file from infecting your Mac.

These core shields are enabled by default when you install Avast Security and allow all permissions. We strongly recommend keeping all shields enabled at all times to ensure maximum protection for your Mac.

To manage core shields:

  1. Click the Core Shields tile on the main Avast Security screen.
  2. Verify the status of each core shield by checking the slider above the shield name:
    • A green (ON) slider indicates that the shield is enabled.
    • A red (OFF) slider indicates that the shield is disabled.
    To enable or disable a shield, click the relevant slider.
  3. Enter the password that you use when you start your Mac, then click OK.

The slider changes to indicate that the shield is enabled or disabled according to your preferences.

Quarantine

Quarantine is a secure vault for detected threats. When an Avast Security scan detects a potentially malicious file, it is moved automatically to Quarantine when you click Resolve on the scan results screen.

When a file is in Quarantine, the following options are available:

  • Delete the file.
  • Restore the file to its original location on your Mac.
  • Send the file to Avast Threat Labs for analysis.

To manage files that are currently in Quarantine, click the Quarantine tile on the main application screen.

Wi-Fi Inspector scans for vulnerabilities when you connect to a Wi-Fi network by checking the status of your network, devices connected to the network, and router settings.
