Excluding certain files or websites from scanning in Avast Antivirus

Although it is generally not recommended, you may want to exclude certain files, folders, 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 Quarantine and submit it to Avast Threat Labs.

Refer to the sections below to manage exceptions in Avast Antivirus:

Add an exception

Setting global exceptions excludes individual files, folders, or websites from all scans and shields.

To set a global exception:
