A relatively new type of software is scareware. This type of malware warns the victim of potential harm that could befall them if they don’t take some action. Typically, this action involves providing a credit card or doing something else to buy a utility they need to clean their system. In many cases, the utility the victim buys and installs is actually something else, such as spyware, adware, or even a virus.

This type of software relies on the ignorance or fear of potential victims who do not know that they are being played.
