Here is a video I found on YouTube about this-

It looks as if the program is supposed to change
the date on which your Rapidshare Premium account
would expire, in order to give you a longer premium
membership.
My guess is it doesn't do that at all, but when you
enter in your log in information, it sends that info to
the person/people behind this program, who then steal
your account, or use it for free.
Either way, the program in the first post looks like it is
something not on the up and up.
The OP should read the rules of the forum about posting
warez.
