it's something that's been noticed, and I can't remember if we know what it is. Tpt isn't malicious in any way though, so next time click 'more options' then allow. I think it's something to do with the tpt server but I honestly don't remember.
Edit:
Nope complete false positive just do the more options thing
I just noticed deactivated GPMP turns PHOT into GRVT, was that added on this update?
