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

  1. Open the Avast Antivirus user interface and select ProtectionVirus Chest.

OR

  1. 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 (threats which cannot be repaired or moved are automatically deleted). You can customize the default actions in the individual settings for each antivirus scan or shield. For more information, refer to the following articles:
