*** It's A Super Virus ?-- Help Me !***

Hello !

I'm Anthony

Now, I have a big problem: I think I meet a super virus

because I used bitdefender v10 ( updated )

but the virus is still exist.

I can recognize it because :

--- it spoil ntoskrnl.exe in C:\WINDOWS\system32

( my win is XP sever pack 1)

Thus when windows start, a message appear :

" Windows couldn't start because the following file is missing or corrupt

<Windows root>\system32\ntoskrnl.exe

Please reinstall the file above "

So I must press F8 twice (or choose " start windows normally" )and then windows open, I can use it

I open windows folder and I see the file ntoskrnl.exe is still exist.

I can affirm the error cause of virus because I tried re copy the file by windows consoles

but windows doesn't still start nomally.

--- When windows open, it minimize and maximize the windows explorer which I open ( automatic )

I can only stop it by clicking right mouse and press ALT + F4

Can you tell me the name of virus ?

Please help me to delete this virus. Thank you very much !

Expect your reply !!!
