Norton Security is removing Auslogics Disk Defrag

Norton 360 for Windows
1

I am running the latest Norton Security v.22.9.4.8 on Windows 10 Pro (1607), which is detecting the latest Auslogics Disk Defrag 7.1.3.0 as a "threat" and then removes it from my PC. To be sure that NS is in fact doing this, I have reinstalled Auslogics Disk Defrag multiple times, and the same sequence of events happen. I have been using both Auslogics Disk Defrag and NIS/NS for many, many years without any problems. This behavior started after the latest NS product update. Here is the sequence of events:

  1. Auslogics Disk Defrag 7.1.3.0 is installed. It runs fine for one or two days thereafter.
  2. One or two days later, I get a "Security Request" window from NS. It goes along the lines of "Your computer must restart to continue removing Security Risks."
  3. I click on "OK" to restart Windows 10.
  4. Once the restart completes, Auslogics Disk Defrag is no longer a program on my PC. (No Start shortcut; No reference of it in Control Panel > Programs and Features)

Any help is appreciated. Thanks.
