I typed in the sfc /scannow and surprise! It asked for my Windows XP Home Edition CD. I could not find any with my original purchase material, just a Magnell Recovery CD and a small booklet, which said the Microsoft Certificate of Authenticity was attached to my PC. Yes it's on top of the CPU.
I put the Magnell Recovery CD in, and the scannow started choking, saying that "Files are required for Windows to run properly must be copied to DLL cache. Insert your Windows XP Home Edition CD-ROM now." When I clicked Information, it said "You inserted the wrong CD (i.e. a different Windows product CD than the version installed). (or) The CD-ROM drive in your system is not functioning.
This prompting kept up repeatedly. I exited out of the program unfinished.
As if that wasn't a disappointing result ...
Now my CD player doesn't even start Realplayer when I put the Zevon CD in it. MyComputer does not list the CD Drive D. Realplayer says "No CD drive detected".
It doesn't even make a whirring sound any more when I insert a CD. It did before, but the last few months it was a very loud whir.
Perhaps the CD RW player was on its last legs as a functioning device, unrelated to the trojan???
It still allows me to insert a Cd and eject it. Just won't do anything with it.
