First, verify that the atapi.sys file is no longer in the “C:\Windows\System32\drivers” folder. (If you find atapi.sys in this folder, there may be another problem and this solution may not work.)


Locate a clean copy of atapi.sys from another location on this computer. A simple file search should locate several copies. Use the newest copy listed. Probably from

“C:\WINDOWS\ServicePackFiles\i386:

Copy the alternate atapi.sys file.


Paste the clean copy into the appropriate folder.

“C:\Windows\System32\drivers”

Reboot the computer.

Note: Performing this repair may require removing the hard disk from the affected computer, and connecting it as a secondary or external drive on an unaffected machine.

Access may also be gained by booting the affected system from a cd/dvd boot disk.

Diagnosis:

The removed virus or malware had attached itself to, or infected, the hard disk’s mini-port driver file. Your antivirus software found and quarantined/deleted the infected file. This file is necessary to boot the computer.

The atapi.sys file is usually the affected driver file in this situation.
