Description:
Ransom.prn pretends to be a porn movie player. Instead of showing porn movies it takes the computer for ransom by blocking all input except for a code input box. The code for this box is supposedly to be sent to the user if he pays 450 Rubels. Removal requires user to reboot the computer with another media such as the Spybot S&D BootCD.
Removal Instructions:

Please use Windows Explorer or another file manager of your choice to locate and delete these files.

Make sure you set your file manager to display hidden and system files. If Ransom.prn uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
