This can be a false alarm.
I don’t like it use the Apple update. I just download and re-run the whole iTunes installer. Once I did an update and the CD drive became in-accessable.
www.virustotal.com will scan any file against two dozen anti virus programs. Then in doubt, use that.
CD drive inaccessible?? Wow!
Are you saying I should delete my Apple programs for Windows and then download fresh directly from Apple?
