Glad you got it, that part any way.
Try safe mode or the administator account to rename the file on the desktop. Then reboot and make sure your sound is still woking. If everthing is good then remove it.
If that doesn’t work, open windows explorer, create a folder at c:\ , call it whatever you want, click the desktop folder, find the file in the right hand panel, use the right mouse button to drag it to the new folder and select move.
I googled ‘til the wee hours and found two thing. 1 only one other instance of this file being removed by combofix, but the thread wasn’t finished, so don’t know thw outcome. 2. there is a trojan that uses that name, I had the link, but closed the wrong notepad, Darned if I can remember the search parameters I used. History on this machine if flacky, sometimes its there sometimes it not. :’(
The author of combofix (sUBs) is very diligent and since that is a common file , you’d think there would have been a rash of these. No one that I asked has had this happen. I used combofix in other threads at the same time and there probably where thousand of other usagages at the same time. Perhaps your copy was in fact infected? ???
Your yahoo mic, did you try reinstalling it? and any related software?
DeepFreeze, don’t know. There are other similar programs. I don’t know what would happen if it did get infected. There are other considerations besides updates, down loads would have to be made away from the protection.

Tech plays with these thing, hopefully he will comment. ;D
