Update by user Jul 14, 2021 Numerous robot answered emails that do nothing to solve the problem and only waste time. Original review posted by user Jul 14, 2021 I have a small CNC program from ProtoTrak. It will not run with Bitdefender installed. I have had this problem for years and every upgrade recreates the problem. When Bitdefender was smaller you used to be able to get support from a human. Now all their emails are answered by robots and they just provide an endless series of pointless exercises that do not solve the problem. No humans help. User's recommendation: Ok for generic Windows programs, not for anything technical.
