When you click on a link in the message you will be told that you can pay a fine and not go to jail. The warning messages about going to jail is enough to give anyone pause and for some they pay the fake fine. In all most all cases you will not be able to use many programs on your computer. This prevents users from easily installing removal tools or antivirus software.
