I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.
If d347bus.sys is on your system but you're not sure why or how it got there the only legitimate reason I'm aware of is that you just installed a program called DAEMON Tools probably v3.47 on your system because you want 1 or 10 virtual CD/DVD Rom drives on your system. d347bus. sys is a BIOS driver that installs at start up to trick/allow the system to treat it like a real CD/DVD drive & not a virtual one. It's not a virus or malware (my opinion) but it will be detected by Hijack This & a lot of other programs so if you run virtual CD/DVD drives I wouldn't worry about it, If you don't have any virtual drives there's no reason for this to be on your system.
