Network Inspector - Getting Started

 

Network Inspector scans your current network for vulnerabilities and security issues that may expose your sensitive data, or leave the devices on your network vulnerable to attacks. In addition, Network Inspector shows which devices are currently connected to your home network, so you can see if anyone is using your network without your consent.

Refer to the sections in this article to learn how to use Network Inspector.

Run a scan

To scan your home network for vulnerabilities:

  1. Open Avast Antivirus and go to Protection ▸ Network Inspector.
  2. Click Scan network.
    If you have a VPN enabled, you will not be able to scan the network.
  3. Wait while Network Inspector scans your network for vulnerabilities.
  4. Refer to the relevant information below according to the message you see on the results screen:
    • No problems found on network: We have not identified vulnerabilities or security issues on your current network. Click Finish to complete the scan. Alternatively, click Scan all devices if you are on a private network and want to check all connected devices for vulnerabilities.
    • Problem(s) found / Issue(s) found: We have identified vulnerabilities or security issues on your network. For more information, refer to the Resolve an issue section of this article.

Resolve an issue

If Network Inspector detects issues on your network, you see the message Problem(s) found / Issue(s) found after running a Network Inspector scan.

To learn how to resolve each detected vulnerability, select the type of network you are connected to:

  1. Click Fix issues.
  2. Select Scan all devices to check all devices connected to your network for vulnerabilities.
  3. If you are asked for permission to manage the network, ensure you are connected to a home or private network, then select Yes, continue.
  4. Wait while Network Inspector scans your devices for vulnerabilities.
  5. Secure your connection by selecting Fix issues and following the on-screen instructions.

    Alternatively, view and fix each device's individual vulnerabilities by selecting the drop-down arrow in the relevant panel, and following the on-screen instructions.
  6. After following the instructions to resolve the vulnerabilities, click Rescan network on the main Network Inspector screen to run another scan and ensure that your network is now secure.
