Hi Eddy this is a form of dedicated sink-holing then,
Clever strategy, but counter-hacking malicious payload is a strange way of propagating an AV software.

especially if you neither would like to have Dridex nor Avira's.
According to Dutch law we call this "eigen richting" and it is not allowed according to our judiciary system.
