NOD32 detects a threat but won't delete it

NOD32 keeps finding a file that needs to be deleted and when I hit the delete button I get a message from the AMON file system monitor stating that:

The file "C:\Windows\system32\jkkiigd.dll" will be deleted after the next restart

But it does not delete it after restart. In fact, I keep getting the same threat warning over and over again and i hit delete each time. The warning windows keeps popping up. I've tried to remove it with killbox and hijackthis, but nothing seems to work.

I also get this message:

C:\WINDOWS\system32\jkkiigd.dll - a variant of Win32/Adware.Virtumonde application


and the option to "Clean infiltrations now" but nothing works. I also get a msg telling me that it's in use or being used by another app.

Follow the advice made by Marcos. It worked for me.
