Ransom is a trojan that threatens to delete important files until the user pays the ransom. Once executed, the parasite installs itself to the system, displays some pornographic images and shows a message threatening to delete one file related to installed software or containing user sensitive information every 30 minutes, until the ransom ($10.99) is fully paid. The trojan explains what it does and demands to transfer the money to the hacker’s account. After the user transfers the money, he or she receives a specific number, which allows to uninstall the parasite. Ransom is able to prevent its removal. It launches multiple processes and displays messages when the user tries to terminate the trojan. Ransom runs on every Windows startup.
