My Windows 11 laptop’s c: drive is nearly 100% full over time. More than 50% of the files on the drive are old Norton 360 Virus Definition Files. I know I can uninstall Norton 360, manually remove directories, and re-install.
Does Norton have a tool to gracefully remove the old files? Can you go into safe mode and remove them without breaking Norton 360? How many files/directories should you delete?
Any assistance would be greatly appreciated. If there is a utility download, can you please provide the link?

fwiw ~ my preference is Remove only…with scour File Explorer for remnants and CCleaner - Registry - Scan for Issues + CCleaner…back up the registry before making changes. Just me.
This folder can grow significantly in size, especially if Norton Safe Browser is installed. Users have reported it accumulating over 50GB of data, likely due to retained definition updates.
My drive was full so I did the uninstall / reinstall to get the drive space back. I disabled the Private Browser so I will keep an eye on the space to see if it continues to grow.
AI Overview
When Norton Private Browser accumulates a large amount of data like 50 GB, it is typically caused by a cache file error. In one reported case, a specific file used for security updates grew uncontrollably, filling up the user’s hard drive.
Common causes for excessive data accumulation
Cache file errors: A malfunction in how the browser stores temporary data can cause a cache file (DEFS file, for example) to grow to a massive size.
Security feature malfunction: Some Norton products have internal processes, like the “Fail Safe Delivery” update process, that can incorrectly leave large temporary files that should have been deleted.
Persistent logging: While a browser’s history and cookies don’t typically grow to 50 GB, persistent security and logging features could contribute to large, unmanaged data storage.
General Norton software issues: Other Norton products, such as Norton 360, have been known to cause excessive storage use due to file corruption or faulty logs. Some users reported disk space disappearing rapidly after a Norton update.
How to resolve the issue
1. Clear the Privacy Cleaner:
Open Norton Private Browser.
Go to the Security & Privacy Center.
Click Launch Cleaner on the Privacy Cleaner tile.
Select your preferences and click Clear data. This will delete your browsing history, cookies, and cache.
2. Delete corrupt browser files:
Find the Norton browser’s installation directory, often at C:\Program Files\Norton\Browser\Application.
Look for a large file or folder, such as DEFS, and delete it. This is particularly relevant if your issue matches the known cache error.
If you are uncomfortable manually deleting files, first try the next step.
3. Use the Repair tool:
Press the Windows key, then type Apps and Features and select it.
Find Norton Private Browser in the list, click it, and select Uninstall.
In the wizard that appears, choose the Repair option instead of a full uninstall. This can fix corrupt installation files and often resolves excessive storage use.
4. Completely reinstall Norton Private Browser:
If the repair option fails, a fresh installation may be necessary.
First, use the Apps and Features menu to completely uninstall Norton Private Browser.
Download and reinstall the latest version from the official Norton website.
In the case of a stubborn issue, running the official Norton Remove and Reinstall tool can ensure all previous corrupted files are cleaned up.
Other steps to consider
Check for conflicting programs: Some antivirus products can clash with each other. If you have another antivirus or security suite installed, it could be the source of the conflict.
Monitor background processes: For general performance improvement and to keep an eye on Norton processes, you can use Norton Utilities Ultimate to manage startup and background tasks.
