PRISM Virus "Your computer has been locked due to suspicions of illegal content downloading and distribution" - how to remove?
What is PRISM?
The NSA Internet Surveillance Program PRISM, Computer Crime Prosecution Section message, "Your computer has been locked due to suspicions of illegal content downloading and distribution", blocks computer screens and demands payment of a $300 fine using MoneyPak in order to unlock the system. This is a scam. The message is not related to any legitimate authorities from the USA - it is a ransomware virus created by cyber criminals. The main purpose of this screen-locking message is to scare unsuspecting PC users into paying a bogus fine by making false accusations of law infringements, such as downloading or distributing copyrighted content, watching child pornography, etc.
This ransomware virus infects users' computers using 'exploit kits', which are proliferated via infected email messages, drive-by downloads, and malicious websites. Exploit kits rely on outdated software to infiltrate computers, and therefore, keeping your installed programs up-to-date can drastically reduce the risk of ransomware infection. After successful infiltration, the PRISM virus locks the user's screen and disables all Windows features, which would otherwise allow termination of the fake message. This particular ransomware virus originates from a family called Reveton and targets PC users from the USA. Previous variants of this virus exploited the name of The ICE Cyber Crime Center to scare PC users into paying the bogus fine. The NSA Internet Surveillance Program PRISM "Your computer has been locked!" message is a scam. Do not trust it, since paying the fine as ordered by the message is equivalent to sending your money to cyber criminals.
Cyber criminals responsible for creating ransomware viruses from the Reveton family use IP address information to target PC users from different countries. This is achieved with localized variants of their deceptive, screen-locking messages. To make their rogue messages appear realistic, cyber criminals exploit the names of various authorities and organizations, in this case, the NSA. Other known ransomware viruses use the names of the FBI, ACMA, ICE, etc. in order to deceive PC users into paying the bogus fine to unlock their computers. PC users should be aware that no authorities or organizations, internationally, use screen-locking message to collect fines for any law violations. If your computer screen is already blocked with a message supposedly sent by the NSA Internet Surveillance Program PRISM, use the removal guide provided to eliminate this scam.
