brontok-bl worm that cannot be deleted

im using avast 4.8 home edition and it detected a worm on boot scan. this was the message

File C:\hiberfil.sys is infected by Win32:Brontok-BL [Wrm], Delete: Error 0xC0000043 {A file cannot be opened because the share access flags are incompatible.}

i tried to delete it but it wont work. what should i do?

The file is located in your system restore file.
To disable system restore follow the directions outlined at the following website:
http://www.pchell.com/virus/systemrestore.shtml

Once you’ve done that, re-boot and the restart System Restore if you use it.

Hmmm… isn’t this the hibernation file? I think it could be deleted (maybe in Safe Mode).


C:\hiberfil.sys … yep, I think Tech is right.
