These are usually anti-spyware or security software applications that use various forms of deception and/or unethical means or show a history of negligent false positives to goad the end user to make a purchase.
In some cases these applications maybe downloaded with some form of unwanted software at which point the rogue application is offered to the customer as a way to remove the unwanted software.

Description:
Claims to be an adware remover.
Comment:
It drive-by installs, phones home after install, gives itself the right (in the EULA) to download and install software from its servers, and you have to *pay them* for a "subscription" with a credit card to have it removed, then opt out of having the "subscription" automatically renewed.
Because you must pay to have to removed, some have dubbed this "extortion ware".
