Fcuk they just got the latest payout to a new address and key !!!
how can stop payments until I load a complete new version of core?
I'm going to wipe the drive reformat
That won't necessarily solve the problem. Someone has gotten access to your network, and your physical machine. Your problem could be "internal." I won't go there.
Someone else said it...use a different, dedicated machine running Ubuntu (not Win) and have it do nothing but Core.
