BDAGENT - das ist der Agent des Antivirenprogramms, also gar nicht gefährlich, es ist gefährlich, diesen Prozess zu beenden :)
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.

Best practices for resolving bdagent issues

A clean and tidy computer is the key requirement for avoiding problems with bdagent. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the bdagent.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
