How to Remove PRISM virus (Removal Guide)

The PRISM MoneyPak ransom is a computer virus (Troj/Reveton Ransomware), which locks computers and asks their owners to pay fines for allegedly violating several laws through their online activity.
This screenlocker pretends to be an alert from the PRISM, NSA Internet Surveillance Program and Computer Crime Prosecution Section that states they have detected that you have been viewing child pornography, using unlicensed software, or sharing copyrighted files. They further state that in order to avoid criminal prosecution you must pay a fee of $300 in the form of a MoneyPak voucher within 48 hours to gain access to your computer again.
The malware’s authors prefer these payment services because transactions made through them cannot be reversed and are hard to trace.

The PRISM virus is typically installed on your computer through exploit kits on adult sites or hacked web sites that use vulnerabilities on your computer to install the infection without your permission of knowledge.
If your computer is infected with the PRISM ransomware, this infection will display a localized webpage that covers the entire desktop of the infected computer and demands payment for the supposed possession of illicit material.
The message displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language.

The PRISM lock screen is a scam, and you should ignore any alerts that this malicious software might generate.
Under no circumstance should you send a MoneyPak voucher to these cyber criminals, and if you have, you can  should request a refund, stating that you are the victim of a computer virus and scam.

Because the “PRISM” virus will not allow you to start the computer in Windows regular mode, we will need to start System Restore from the Safe Mode with Command Prompt mode.

STEP 1: Restore Windows to a previous state using System Restore

1. Reboot your computer into Safe Mode with Command Prompt. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard.

If you cannot start your computer into Safe Mode with Command Prompt mode, we can use the HitmanPro Kickstart program to bypass “PRISM” lock screen.

We will then boot your computer using this bootable USB drive and use it to clean the infection so that you are able to access Windows normally again.
You will also need a USB drive, which will have all of its data erased and will then be formatted. Therefore, only use a USB drive that does not contain any important data.

   To create a bootable HitmanPro USB drive, please follow the instructions from this video:
   
3. Now, remove the HitmanPro Kickstart USB drive and insert it into the “PRISM” infected computer.
4. Once you have inserted the HitmanPro Kickstart USB drive, turn off the infected computer and then turn it on. As soon as you power it on, look for text on the screen that tells you how to access the boot menu.
   
   The keys that are commonly associated with enabling the boot menu are F10, F11 or F12.
5. Once you determine the proper key (usually the F11 key) that you need to press to access the Boot Menu, restart your computer again and start immediately tapping that key. Next, please perform a scan with HitmanPro Kickstart as shown in the video below.
   
6. HitmanPro will now reboot your computer and Windows should start normally. Then please Malwarebytes Anti-Malware and HitmanPro, and scan your computer for any left over infections.
