If your computer is locked, and you are seeing a “Your computer has been blocked” notification,then your computer is infected with a piece of malware known as Trojan Reveton.
The “Your computer has been blocked” notification is a computer virus, which will display a bogus notification, that pretends to be from the official law enforcement agency and states that your computer has been blocked due to it being involved with the distribution of pornographic material, SPAM and copyrighted content.
The “Your computer has been blocked” virus will lock you out of your computer and applications, so whenever you’ll try to log on into your Windows operating system or Safe Mode with Networking, it will display instead a lock screen asking you to pay a non-existing fine of 300$ in the form of a Ukash,MoneyPak orPaySafeCard code.
Furthermore, to make its alert seem more authentic, this virus also has the ability to access your installed webcam ,so that the bogus “Your computer has been blocked” notification shows what is happening in the room.
The “Your computer has been blocked” notification is used by cyber criminals alongside the name of known international law enforcement agencies like Federal Bureau of Investigation (FBI),Europol and Central Intelligence Agency (CIA), or local law enforcement agencies like: West Yorkshire Police,Metropolitan Police and The United States Department of Justice.
Under no circumstance should you send any money to these cyber criminals,as this could lead to identity theft,and if you have, you should contact your credit card company and dispute the charge stating that the program is a scam and a computer virus.

“Your computer has been blocked” Ukash Ransom has modified your Windows registry and added its malicious files to run at start-up, so whenever you’re trying to boot your computer it will launch instead its bogus notification.To remove these malicious changes, we can use any of the below methods :
Method 1: Start your computer in Safe Mode with Networking and scan for malware
Some variants of “Your computer has been blocked” virus will allow the users to start the infected computer in Safe Mode with Networking without displaying the bogus lock screen. In this first method, we will try to start the computer in Safe Mode with Networking and then scan for malware to remove the malicious files.
- Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
- Press and hold the F8 key as your computer restarts.Please keep in mind that you need to press the F8 key before the Windows start-up logo appears.

If this occurs, instead of pressing and holding the “F8 key”, tap the “F8 key” continuously until you get the Advanced Boot Options screen. - On the Advanced Boot Options screen, use the arrow keys to highlight Safe Mode with Networking , and then press ENTER.
- If your computer has started in Safe Mode with Networking, you’ll need to perform a system scan (as seen on STEP 2) with Malwarebytes Anti-Malware and HitmanPro to remove the malicious files from your machine.

Hello Henry,
Is this your personal computer/ laptop or from work? Please note that HitmanPro doesn’t not offer the 30 days trial for corporate machines, however if this is your personal computer, you should be able to activate this product key.
Anyway,lets see if we can get rid of some of malware by using the below software:
STEP 1: Run a scan with RogueKiller
RogueKiller Download Link (This link will automatically download RogueKiller on your computer)
STEP 2: Run a scan with Emsisoft Emergency Kit.
EMSISOFT EMERGENCY KIT DOWNLOAD LINK (This link will open a download page in a new window from where you can download Emsisoft Emergency Kit)
STEP 3: Run a scan with Eset Online Scanner.
ESET Online Scanner Download Link (This link will automatically download ESET Online Scanner on your computer.)
NEXT,please re-run a scan with HitmanPro and click on “Save log” and post that here so I can take a look at what it has found.Then, I’ll give you instructions on how to remove the left over files.
Good luck!
Used method 3, and it worked great. Removed the ransomware with no problem. Only thing you need to be aware of is that HitmanPro will not remove the malware without buying an Activation key.
Thank you so much! I was freaking out for a good minute before I figured it was probably a virus.
I was able to successfully use Method 1 and the Malwarebytes download
Thank you … i used method 3, took a while but was able to remove the malware. Thank you very much for the instructions – very clear and easy to follow.
Thank you! I have used Method 2 for my Windows 7 x64 and it worked! :)
