Answer 1

On the Task Schedular tab in Autoruns are two yellow entries for Adobe, uncheck both of those and then restart your PC to apply that change, and wait to see if that solves the problem.

Answer 2

Hi, I checked and it's still popping up randomly.

On the Scheduled Tasks tab in Autoruns, uncheck the 3 Firefox entries (shown below), then restart your PC to see if that stops the PowerShell popups.
