My VPN suddenly started not connecting and I receive a message requesting me to upgrade. I have enabled installed / reinstalled the program, restarted, contacted Support, entered a series of commands and restarted. I allowed a Bitdefender support individulal who called me from the support site to sign into my laptop. They went to a website called Cover my tracks and then told me that my network was not secure. They requested I pay $249 for a Bitdefender plan that they would not give me any information on and became angry when I tried to search online to learn more. I disconnected, changed my Bitdefender password with the same resulst. What is going on?
