I've just installed DisplayFusion 10 B26 in order to fix the taskbar icon issue in Win 11 (thanks!)
During the install, I received 4 "Data Protector" Norton alerts, 2 regarding DisplayFusionSetup.exe during install, then 2 more after rebooting regarding DisplayFusion.exe.
In all instances, the alerts were "Data Protector blocked a suspicious action by DisplayFusionSetup.exe" (or DisplayFusion.exe)
The files were
C:\Program Files (x86)\DisplayFusion\RollupImages\1.png
C:\Program Files (x86)\DisplayFusion\RollupImages\10.png
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default\Extensions\ammjkodgmmoknidbanneddgankgfejfh\3.0.1_0\assets\sound\ping.ogg
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default\Extensions\ammjkodgmmoknidbanneddgankgfejfh\3.0.1_0\icon\icon-128.png

Edited to add the "Action Observed" is "Suspicious process attempted deleting a file protected by Data Protector"

Just wanted to update that I don't think this is necessarily a DisplayFusion issue, although the files it was trying to delete are odd...
I got a Norton "Data Protector" alert when trying to edit a file that Notepad++ told me needed Admin mode. I don't know if this is a new Norton feature or something I accidentally turned on, but you can probably consider this issue closed.
