What happens when you delete Avast

Specific to Avast

Paid features remain linked to your account or activation code rather than the local installation. You lose active security shields and the ability to manage quarantined files locally. Deleting the app alone does not remove stored data, which typically ranges from 200 MB – 2 GB across various folders.

Where your Avast data lives

Avast keeps none of your own files in its folders; what it stores is rebuilt automatically or comes from your account.

Account and sync: Paid features are tied to your Avast account or activation code.

Data left behind by Avast

User settings and logs stay in ~/Library/Application Support/Avast after removal. System-wide virus definitions, engine files, and quarantine also persist in a separate library folder. These directories and your personal documents remain on the disk until you remove them separately.

Frequently asked questions

Will deleting Avast delete my files?

No. Removing the app doesn't touch documents you saved in other folders. Only the app and, if you remove them, its own support files are deleted.

Why should I use the internal Avast uninstall tool instead of the Trash?

The official tool ensures background services and system extensions are fully removed.

Will I lose my paid subscription if I delete Avast?

No, because paid features are tied to your account or activation code.
