On Sept. 14 I had a pop up on my screen and it was the exact same that pops up when I turn the computer on to allow my Cyberspace program to work. I pressed OK and the computer shut down. I have tried everything - can't even restore the computer to an earlier time, get to safe mode to do a virus check, etc.
This is what came up:
Boot critical file D:\CIdII is corrupt (not sure if CId should be ii or II or 11) PROBLEM: Signature 07
The computer has no memory problem.
If I have to use the DVD's I had made to recover the computer, how can I be sure the virus is gone?

Please go to our Spyware, Adware, Viruses and Malware Removal forum. Read the first sticky Read This First - IMPORTANT Instructions (updated 6/9/2011) and follow the directions it provides.

Thanks for your suggestion - but can't get on the Internet on the computer with the virus.

Do it from another computer (the one you are posting from). Download files as required and put them on a flash drive or CD to use on the infected computer. Then post results by copying back to a flash drive or CD then posting from a working computer.
