How to Delete a File Which is Unlocked/Under system Use?

does not allow deleting files because they are being used by
any application.

file from task manager process tab, about which you do not know. But sometimes we want to delete some suspicious files which are under use
of some nasty virus or malware. If this is the case, KillBox can help us.
