Excluding certain files or websites from scanning in Avast Antivirus

While it is generally not recommended, you may want to exclude certain files or websites from scanning to speed up your scans or to avoid false positive detections.

Set exceptions only if you know that the files and websites you want to exclude are not infected. If you are unsure about a file, you can scan it in Virus Total, or add the file to the Virus Chest and submit it to the Avast Threat Labs. For more information about Virus Chest, refer to the following article:

Add an Exception

Setting global exceptions excludes individual files, entire folders, and websites from all scans and shields at once. Scans and Shields analyze all file, application, and web activity in real-time.

To define an exception for all scans and shields:

  1. Open the Avast Antivirus user interface and select MenuSettings.
  2. Ensure the General tab is selected, then click Exceptions.
  3. Click the Add Exception button.
  4. Add an exception in one of the following ways:
    • Type the file path, folder path, or URL into the text box, then click Add Exception.
    • Click Browse, tick the box next to the file or folder you want to add to the exceptions list, then click OK.
  5. Your selected file, folder, or URL is added to the exceptions list.

View the Exceptions List

After you specify a file, folder, or website to exclude from Avast Antivirus scans and shields, you can view and remove any item from the list individually:

  1. From the main Avast Antivirus user interface, go to MenuSettings.
  2. Ensure the General tab is selected, then click Exceptions.
  3. Ensure the boxes next to File/Folder and Website are ticked to see all exceptions in the list. The Exceptions list is visible below these filters.
  4. To delete an item from the list, hover the cursor over the panel for the exception you want to delete, then click the trash icon. The list will update automatically.

The complete Exceptions list is now visible.
