There is no actual rating for this file as it is a Microsoft authorized driver file, a .dll. Yet it is initiated when an application you install requires a hole through your firewall, so its authorization is from you, but may have hidden intent. The adjoining article here fails to mention this completely, being more interested in selling you their program and self-interest blinded to the true malice this file may or may not hold. If their interest in your computers safety has any similarity to their failure to process this simple file and explain ti to you, you might consider looking for another program than this.
