It is a Bitdefender executable file, that often remains on the computer and interferes with other programs. Go to, and save the program to your computer, then run it. It should clean up all files, including bdagent.exe

I know that I won't use your web site again because you're are not being sincere with the info and are creating a fear rather than explanation like for example
I just want the file off my computer. it has caused me all kinds of grief in that I have security software and I got this dam thing by error (I think through Safepay). It is a cute trick by Bitdefender to give you the file and then try to sell you software to get rid of it. There should be a law.
