0 software designed by criminals to prevent computer users from getting access to their own computer system or files unless they pay money:
Ransomware payloads utilize elements of scareware to extort money from the system's user.
Ransomware affects an infected computer in some way, and demands payment to reverse the damage.
The transaction results in a ransomware virus infecting the deal broker's laptop, which contains the only copy of the database.
Some new viruses, particularly ransomware, use polymorphic code to avoid detection by virus scanners.
This model is also called ransomware.
Some forms of ransomware encrypt files on the system's hard drive (cryptoviral extortion), while some may simply lock the system and display messages intended to coax the user into paying.
