How long does the devfee usually take? I just saw that "Devfee: Stop mining and disconnect"

Is the claymore chargning anything us, or the nanopool that I'm using, how much is the fee and how often does this happen (if more than once)

At the other side I'm very statisfied with claymore, I had an issue today as the windows defender is counting it as a threat/virus and deleted the files, but I got it solved by excluding the folder so the antivirus won't scan it.
