How to Completely Uninstall Avast on Mac
To remove Avast completely, use the built-in uninstall option rather than dragging the icon to the Trash. This ensures all security components and system extensions are fully deactivated.
Remove Avast and everything it leaves behind

Avast has its own uninstaller

- Empty the Trash to free up the space.
Everything Avast keeps on your Mac
2 locations. Tick each one as you remove it; back up anything marked as your data first.
Locations are the standard macOS folders Avast uses; some appear only after you use the matching feature.
Why dragging Avast to the Trash is insufficient
Specific to Avast
Simply moving the application to the Trash leaves background services and shields running on your Mac. System-wide folders containing virus definitions, engine files, and quarantine also remain, occupying 200 MB – 2 GB of space. These directories and the user library persist until removed separately.
- Background items
- Shields run through background services and system extensions that remain if only the app is deleted.
- Account and sync
- Paid features are tied to your Avast account or activation code.
Preparing to uninstall Avast
Review the quarantine area to restore any necessary files before starting. Ensure you have your activation code or account details since paid features are tied to them. Separate steps are required to remove browser extensions if you installed them.
