How can I permanently remove this virus from my hard disk?

Question

Well,I have some kind of big virus that's infected my hard disk and I can't seem to remove it even if I install new windows XP and delete everything from my computer.I already reinstalled new windows 3 times,and it works for 2 days and then crashes with this same message saying "we cannot start windows because one file is missing: ntskrnl (or something like that).

Does anyone at least know what kind of virus is this?

I didn't even go to internet when I reinstalled new windows or anything so I don't think that everytime it's a new virus...

Is my hard disc completely destroyed or is there a way to remove that virus so my computer could function normally?

Thanks in advance!

Answer 2

If you format the computer everything is removed including viruses.

I suspect from the error message you are getting it the the boot sector of you hard drive that is failing or is bad. When Windows is installed it writes a data file to that section of the hard drive successfully. Then after several times needing to read that data block it is unsuccessful and the computer crashes.

New hard drive time.

Answer 3

You have a hardware failure, most likely the hard drive. Buy a new one and then install Windows.

Answer 5

it's probably not a virus but a corrupt system file.

you will need to boot from the Windows XP disc from your CD drive and you can reformat completely. Do not select repair in this case.

if your version of XP is not the SP2 (service pack 2 version), get that and you can extract ntoskrnl.exe from this file.

so what i'm recommending is you will need to replace the file and it should be okay afterwards.

Answer 6

Hardware failure is indeed likely (just replaced a hard drive in a workstation with a similar symptom) but that is not the only possibility. It could be that there is a problem with the software you have installed, it could be that when you reinstall you are not removing the virus, but just adding files, it could be that you are reinfecting with some other program you don't even recognize as infected.

The best solution is probably:

Format the drive, don't just reinstall, but format the drive and repartition so that you have multiple instances of Windows.

Personally, I like System Rescue CD for this.

Back up periodically. What you'd probably be best served by is three partitions, something like Clonezilla on the first, Windows XP on the second, and a backup of Windows XP on the third. Periodically you'd backup the second partition to the third with ntfsclone and that way, when one Windows install goes belly up, you'll be able to switch to the other, provided the hardware is not hosed. If the hardware is completely hosed, you'll know it because both instances of Windows will become simutaneously unavailable. Possilby you can even work around bad sectors by installing with this method.
