Killbox is a great spyware, adware and malware killer. It is very powerful software so it should only be used when instructed by a professional.

The creator of this freeware is Option^Explicit

Pocket KillBox is the upgraded version. It is a program that can be used to get rid of files that stubbornly refuse to allow you to delete them. You type the full path of the file you would like to delete in the field and press the Delete File button (looks like a red circle with a white X).
