[SOLVED] Computer won't restart: "Root cause found: Boot critical file D:\CI.dll is corrupt."

I was using the computer when all of a sudden it shut down. When I turn it back it on, it automatically tries to do a Startup Repair. After several minutes, I get the message: "Startup Repair cannot this repair this computer automatically." When I click on "View problem details," everything looks fine except for "Root cause found: Boot critical file D:\CI.dll is corrupt." This happens every time I try to retart the computer. I've tried System Restore and System Image Recovery to no avail.

Thanks in advance for your help.

Can you try using the following tutorial to see if you can use SFC to replace the corrupt dll file?

This tutorial should explain how it works:

Ian,

Turns out the computer had a rootkit virus, and Kaspersky TDSSKiller removed it. Thanks anyway.

I'm having the same problem, so could you please tell me how you fixed it? I'm begging you. I've done everything I know how to do.

startup repair does nothing.
system restore does nothing. Actually, system restore will run successfully, but it ultimately doesn't change a thing.

I can't get past startup repair, so how on earth am I going to fix this?

As GW7777 found. Do a full scan with your anti virus program and accept any "fixes".
P.S. Some free anti virus programs do not scan for root virus's

You might also try RKill and the freeware version of Malwarebytes. Both are listed in our Freeware DB.

How do you run a rootkit cleaner when the computer won't boot?

If your machine won't boot from the HD (and I assume you've already ruled out hardware failure) then you set your BIOS to boot from CD and you start-up with the system disk.

Hi,

First of, thank you for taking the time to even read this!

Secound, I saw you had the same problem like me, with the corrupt boot.

So, the Q is: How did you run the TDSSKiller when you can't boot the computer?? Appreciate the help mate!


Sincerly,

Oliver from Sweden!

EDIT: Saw you said to use the start up disk, but how do you run the application??

Hopefully the System Repair feature can fix you to a point where you can boot. If not then a complete reinstall or recovery from your back-ups may be necessary. Unfortunately viruses/malware do not play nice, that is why we strongly recommend a regular back-up schedule to an external drive or online storage facility.
