700+ processes and they're gone

I just launched CCleaner and (I like spectating Task Manager) then I noticed processes called TUAutoReactivator64.exe appearing constantly while CC didn't appear at all. For a moment there were 700+ of them. I relogged and they were gone.

I have TuneUp installed and had CC disabled from background running. I removed it from the list and it works normally.
Still it's not good it makes hundreds of processes, that could get fixed.
