Can someone explain to me what this is?
Ive tried to google it and all it has is a bunch of software downloads to remove the error.

Could you give us the exact error message? or maybe a screenshot of it?
Also, tell us when you're having this problem, or if it's just happening randomly.

Saw the first link and only read up to hardware.
Also figured itd be better to post this here and not under general help.

Its happening on someone else's computer randomly, her mozilla is also freezing up.
My mozilla was having the same problem and the only changes ive made to my computer would be an update with adobe and an update for my pc when it shuts down.
I reinstalled my mozilla and that fixed the problem however I figured the rundll error had nothing to do with mozilla and it was her pc.
