FBI – Your PC is Blocked

Another addition to the list of ransom software is the one that mimics Federal Bureau of Investigation (FBI). AVG uncovers this malware and believes that it is distributed through Blackhole exploit kit. This malware can enter the computer through security breaches that attackers may discover on a target computer. Once inside the system, the malware will lock the desktop and display a message that purports to be from FBI. It will proclaim legal action against the user who violates Copyright laws for illegally using or distributing copyrighted contents.

This message will demand user to pay a $100 penalty for this offense through MoneyPak. This method is a payment system that allows user to buy credit from any partner convenience store and use the value to purchase online. This process obviously reveals that FBI is not in any way connected to this fraud activity. Most of the text that lies in this ransom page is copied from previous ransom malware that belong to the same group.

Part of the message that appears on this fake copyright violation page reads:

Federal Bureau of Investigation
Location: United States
IPS: GTS Central Europe
Your PC is blocked due to at least one of the reasons specified below.
You have been violating Copyright and Related Rights Law (Video, Music, Software) and illegally using or distributing copyrighted content, thus infringing Article I, Section B, Clause 8, also known as the Copyright of the Criminal Code of United States of America.

It is believed that there are several variants of this FBI virus. Security experts from Symantec categorized this group as Trojan.Ransomlock.R. Thus, you may use Symantec’s removal procedure to stop FBI virus from blocking your PC.

    My computer got infected today, couple hours ago. I followed everything you’ve listed and was able to delete some Trojan viruses but still have the FBI page pop up. Is there something I missed? If you could help me out that would be great.

  2. AvatarJack

    DC, have you run the windowsunlocker tool? What happened, did it detect some virus?

    My computer got something like this virus few weeks back. I just update my antivirus program and restart my computer is Safe Mode. I run a scan there and it found some Trojans. I remove them and restart the computer again. Next, I use System Restore and set the computer to load my latest restore points. That solved the problem.

  3. AvatarDC

    I did do the windowsunlocker but it didn’t seem to do much. I don’t think it really deleted anything.

    I did everything regarding the kaspersky program and was able to remove some Trojan viruses but still having a problem. Basically my windows still seems to be locked and the FBI Moneypak page keeps popping up every time I restart the computer normally. Perhaps I should try restoring my computer to a previous restart point.

  4. AvatarDC

    So my computer seems to be fine now! I actually followed what you did. I scanned for viruses in safe mode and it found something and I removed it. Restarted my computer and no pop ups or anything. So thank you for that. :) though I want to make sure everything is fine. Are there any antivirus programs you could recommend me? I’d really appreciate that.

  5. Avatarron

    everyimte i try to run the program to run this virus blocker and it says the iso is corrupt . what am i doing wrong?

  6. Avatarron

    I get to the part where you accept the agreement and then my computer just shuts off. What am I doing wrong?

  7. Avatarron

    After i get this done do i still need too keep booting up from this flash drive or do i go back to normal boot up.

  8. AvatarDC

    Well after you’ve done all that we’re you able to remove any viruses? If so, you should still try booting into safe mode with networking and use an antivirus program to scan for any other viruses that we’re missed. After that try restarting your computer normally.

  9. AvatarDC

    You should still scan for viruses in safe mode even if you weren’t able to remove anything before.

  10. Avatarmary

    my moms Laptop got this today ! && all i did was restore her Computer & it took it off(:! So just restore it it should take it off !

  11. Avatarantjuanroy

    I followed these directions to a key and it worked perfectly. That FBI thing is no longer on my computer. Thanks a lot. The only suggestion I have is to change Step 1 into- “put infected computer into safe mode in order to download the Kaspersky files”. I’m not very computer savvy so it took me a while to figure this out. As a newbie I was wondering how to download the files when the FBI thing wouldn’t allow me to access the internet. But after that it was smooth sail very easy to follow. Thanks a lot for the post.

  12. AvatarRonald

    I simply did a system restore, and everything seems fine.

  13. AvatarVon

    Malwarebytes worked for me. Boot into safe mode with networking, DL the free version + install it and run a quick scan option. Was back up & running in 30 minutes. Malwarebytes.org is the site.

    A Lot of sites want you to buy a service to remove this or go through these complicated steps. this seemed like the simplest route to go & it worked.

  14. AvatarRicardo

    I got hit yesterday, went out and bought moneypak for $200 dollars. After all I was guilty of everything, and they said I’d get 12 years in prison for. But then I went to another computer because mine was blocked, and read all about the ransomware FBI scam. Luckily I didn’t use my moneypak card knowing I was guilty. That was yesterday, today I booted up and I wasn’t blocked and haven’t done anything to clean my pc yet. But from what I read yesterday, it’s only a matter of time before it surfaces. Do you think I should still clean it? I have Charter Security Suite protection, but it didn’t help me yesterday. The suite is an Fsecure anti everything product supposedly. That FBI thing scared me to death. Cured me from looking at stuff I shouldn’t. I plan on being an angel from here on out, Amen.

  15. AvatarMerbil

    Definitely, you should run a scan with Malwarebytes and other antivirus program. I heard that this virus can contact a home server and download other threats onto the computer. It may surface any time with much destructive effect.

  20. AvatarRuby

    @FINDU Yes, I saw that message one time and my web cam was turned on and not by me – I immediately did a hard shut down on PC – not sure If I should do more…..

  21. Avatared55

    Thanks for the suggestions. tried the manual method but could not find the virus files. I then did a restore and that worked. Happy now!!!

  22. Avatarec55

    I got this thing a few months ago. Mine turned out to be “User” specific. Luckily, when I set up my computer I included a “Guest” access. I just signed on to it and ran my Norton. It took care of the problem and I haven’t been bothered since.

  23. Avatarjessejay

    This FBI ransom virus blocked my PC yesterday. I was able to remove it by following the instructions above. Right after the first scan, I see that my computer is unlocked from the FBI virus. To remove entire traces, I also run virus scan, which are not covered in the removal procedure from this page. Here’ what I have to share.

    Download and run Microsoft Safety Scanner. It found a bunch or threat after the test. It may or may not be relevant to FBI blocking virus, at least, it has removed hidden threats. You can download MS Safety Scanner here: http://www.microsoft.com/security/scanner/en-us/default.aspx

    Aside from Kaspersky, I also scan for rootkits using McAfee’s tool. This stand-alone utility manages to remove rootkits as well as complex Trojan. It did not find any virus, but some components are identified and removed from my computer. Get RootkitRemover from McAfee’s web site: http://www.mcafee.com/us/downloads/free-tools/rootkitremover.aspx

    Lastly, I did online virus scan using Avast free interface. I used it to scan some files under my UserProfile folder. It turns out that these files are harmful. Start scanning your PC with Avast Online Scanner here: http://onlinescan.avast.com/

  24. AvatarJoe M.

    My compter was blocked with the FBI logo, I powered down the computer, powered up press the F1 key, slected F8 in SAFE MODE, slected Logon with network, went to START typed system restore, ran restore with last check point. System restored to last picture. Restarted windows, after windows came up OK , restarted system again in SAFE MODE. ran Microsoft Essentials full scan runs faster in this mode. Cleaned up any virus found. Restrated Windows in normal mode.
    Created a new check point with system clean.

  25. Avatarmat

    .I received the FBI message and I tried to restart my computer and when I do safe mode it seems like it’s starting up but then I get a white screen and after a couple of minutes I get the FBI symbol againwhat can I do to get this FBI message of my computer

  26. AvatarKolby

    So this popped up on my computer earlier today and I went through your steps and restarted my computer in safe mode, however this virus still pops up in safe mode? What am I doing wrong?

  27. Avatarantitroj

    @Kolby, in that case you should make the Kaspersky Rescue Disc from another computer. Boot from the USB to bypass the virus actions on Windows. Rescue Disc runs on Linux so there’s no way that FBI virus can interfere with. Once you boot the computer using the USB, run a full scan.

  28. AvatarLucas

    My computer just got infected last night. I got to the safe mode part, but then the pop up came up in safe mode! I don’t know what to do, because i cant do anything with my computer now. I’m having to use another to get to this web page. Can someone please help me?

  29. Avatarmorfo
