I did have to go to the Activity Monitor and stop them from running, but then trashed as advised.

Sure you can try that...

if not, reboot into SafeBoot mode this might keep them from launching to get in there and delete if not needed.

A SafeBoot Start up your Mac in safe mode - Apple Support

third party system modifications and system accelerations are disabled temporarily.

Simply reboot as normal to get out of the SafeBoot mode.

Using Tahoe 26.5 on my 2023 iMac with M3, I am now getting the following repeated popups after login:

“USBserver.app” would like to access data from other apps

“WorkflowAppControl.app” would like to access data from other apps.

I have also gotten a "Netserver" message. Looking at old threads, I cannot find and such apps with the Finder.

The only recent addition, besides the OS updates, has been the addition of Yubikey registrations and Yubi Authenticator. Whether I choose Allow or not, the messages re-appear next login.
