Background Intelligent Transfer Service missing!!!

Hi,

I've got a Dell Inspiron with 64-bit Windows 7. My Windows Update is not working and I get an error message 80246008 and on top of it all, my BITS is missing, can't find it anywhere...

Have tried to follow the steps in Help and Support without any luck, also tried the Fix It-program without luck as well.. Really need help with this and hopefully avoid restoring the laptop to it's original factory state...

This is really annoying, haven't been able to update any vital files at all...

Because of these issues my McAfee firewall's not working either...

Please help as soon as possible!!
