Why am I unable to safely remove the USB hard drive from Windows if I have BitDefender Antivirus 2010 installed? When I try to safely remove the USB hard drive I get an error The device 'Generic volume' cannot be stopped right now. Try stopping the device again later. This error continues even if I disable AntiVirus Shield and the only way to stop the drive from being in use is to uninstall BitDefender. Once I uninstall BitDefender I am then able to safely remove the drive.
