Using the Virus Chest in Avast Antivirus

The Virus Chest is a safe place in Avast Antivirus for storing potentially harmful files and completely isolating them from the rest of your operating system. Files inside the Virus Chest cannot be accessed or run by any outside processes, software applications, or viruses.

Access the Virus Chest

Access Virus Chest in one of the following ways:

• Open the Avast user interface, then go to Protection ▸ Virus Chest.
• Right-click the Avast icon in your system tray and select Virus Chest.

Move files to the Virus Chest

Avast Antivirus automatically moves malicious files to the Virus Chest if they cannot be repaired. You can customize the default actions in the individual settings for each antivirus scan or shield. For more information, refer to the following articles:

• Adjusting settings for Avast Antivirus scans
• Adjusting settings for Avast Antivirus shields

To add files to the Virus Chest from the Virus Chest feature screen:

1. From the Virus Chest screen, click Add File....
2. Locate the file you want to move to the Virus Chest ('sample.exe' in the example below) and click Open.
3. The file now appears in the Virus Chest and can be sent for analysis.

Restore files from the Virus Chest

To return a file to its original location:

This option will restore the file to its original location on your PC. We recommend using this option only if the file is safe from malware.

1. Tick the box next to the relevant file in Virus Chest.
2. Click the … icon (three dots) next to the Delete button and select Restore from the context menu.
3. Click Close in the confirmation dialog that appears.

2. Click the … icon (three dots) next to the Delete button and select Restore and add exception from the context menu.
3. Click Close in the confirmation dialog that appears.

Submit files from the Virus Chest to the Avast Threat Labs

Before restoring files to their original locations, it's important to be sure they are clean. To ensure your PC stays protected, send files to the Avast Threat Labs for further analysis. We recommend sending the following file types:

• Potential malware: files that Avast has not flagged as malware, but you believe may be malicious.
• False positive: files that Avast has identified as malware, but you believe may be clean.

1. Tick the box next to the relevant file in Virus Chest.
2. Click the … icon (three dots) next to the Delete button and select Send for analysis from the context menu.
3. In the form that appears, tick the relevant box and provide any details related to your issue, then click Send.
4. Click Close in the confirmation dialog that appears.

Delete files from the Virus Chest

1. Tick the box next to the relevant file in Virus Chest.
2. Click the Delete button at the bottom of the Virus Chest screen.
3. Click Delete in the confirmation dialog that appears.

Manage Virus Chest settings

By default, the Virus Chest is allocated a maximum space of 5120 MB, but can be changed in Virus Chest settings. To configure Virus Chest space allocation:

1. Open the Avast user interface.
2. Go to ☰ Menu ▸ Settings.
3. Click Protection ▸ Virus Chest.
4. Click into the text box and redefine the maximum size of your Virus Chest.

The Virus Chest space allocation is now configured.
