You should bear in mind that right now there are many of such similar computer infections which try to infect as many PCs as possible. This virus is correctly classified as ransomware because its main purpose is to push users into paying the ransom for unlocking the computer. The malware acts quite aggressively in its attempt to attack as many PCs as possible.
The virus is presented in the form of a fake warning supposedly originated by Computer Crime Prosecution Section. It states that the user was found to perform a lot of illegal activities online, primarily having to do with the following illegal activities:
