Akala EXE Lock can protect any executable file from non-authorized execution. It asks each time the program is loaded the password you have set. If you're not the only one who has access to your computer then I'd bet that there are certain programs and files you don't want others accessing. There are a multitude of options on how to go about doing this. There are encryption programs, programs that restrict access to portions of your computer, programs that make your files invisible. You get the general idea. A novel approach to the problem lies in Akala EXE Lock.
