Recently, I have discussion on the topic on Symantec forum: see https://community.norton.com/en/comment/6692471
There are some strong comments there:
- Norton Product Tamper Protection is preventing CCleaner from incorrectly removing this registry entry and damaging your Norton installation
- CCleaner being unable to delete your Norton-related registry item, that is a detection of a legitimate or orphaned Norton registry entry by CCleaner and not something that Symantec needs to fix
- If you use a registry cleaner on a regular basis, you might want to read the Microsoft support article Microsoft Support Policy for the Use of Registry Cleaning Utilities
(link is external), which states in part:
"Some products such as registry cleaning utilities suggest that the registry needs regular maintenance or cleaning. However, serious issues can occur when you modify the registry incorrectly using these types of utilities... Microsoft does not support the use of registry cleaners."
So, i'd like to get piriform comments on that statements
