Norton History List

What does "Unauthorized access blocked (Access Program Data)" mean. I get some 20+ items as "Medium Severity" and all "Blocked". This a daily listing.

Re: Norton History List

The Unauthorized Access Blocked messages in your security history are logged by Norton Product Tamper Protection every time an executable file attempts to read/write/edit/delete a Norton file.  Common Windows processes like svchost.exe, taskmgr.exe, dfrgntfs.exe, etc. as well as any executable from third-party software like CCleaner and Malwarebytes Anti-Malware will cause one of these Unauthorized Access Blocked messages to be logged if they touch a file from your Norton installation. Please see my post <here> in the Product Suggestions board regarding logging of these blocks. (credit Imacri)
Norton Product Tamper Protection prevents outside programs from making changes to the Norton product.  Norton Product Tamper Protection protects your Norton product from an attack or modification by any virus or other unknown threat. Norton Product Tamper Protection view in the Security History window displays details about unauthorized attempts to modify Norton processes.  Unauthorized access blocked (Access Process Data).  NPTP events are not reports of malware.
The most common NPTP log entries are legitimate Windows processes that Norton is preventing from accessing Norton files or processes.  Norton is simply maintaining a secure isolation from other processes running on your system.  (credit Community)

Re: Norton History List


Thank you for your quick and detailed reply on my question. I did read the associated forum posts and guess I wasn't the only one questioning the entries. I feel good about the History reports entries now that I know what they mean.

Thanks again
