I just got a notice from my Bitdefender Ransomware Protection that it has blocked cnsemain do exe from running--it doesn't like the looks of cnsemain at all and the bit of reading I've done on it tells me that I should leave well enough alone. Since it's not essential, I'm not going to allow it to run.
