No problem...most posters are so busy trying to make the urgency of their situation clear...that they omit basic details in the post that might be useful...you're not the first, you won't be the last
What is the exact wording of the error message you received...and when does it appear?
From what I see, the file you mention is either malware or insignificant...no one seems to have a clue.
Exact wording, please...thanks.
As for your CD drive....take a look in Disk Management and tell me if it is reflected there. Then...take a look in My Computer and tell me if it is reflected there.
Then take a look in Event Viewer, looking for any errors that relate to any drive (Disk 0, Disk 1, etc.).
