A malware has hijacked my Computer. When you turn it on a screen pops up stating that my computer has been blocked by the department of justice and I will have to pay $300 to unblock it. I am unable to start it in any of the safe modes. I started the computer with a flash drive and ran windows defender. It found some malware and had them deleted but did not cure the problem. I also used a Kaspersky rescue disk, this also found several suspected malwares but again still did not correct the problem when i restarted the computer. I also tried Hitmanpro, but to no avail. Any help or advice would be greatly appreciated.

Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:
  • At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
  • Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
  • Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
  • Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  • All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
  • If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
  • I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
  • Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  • Please attach all report using

    button below. Doing this, you make it easier for me to analyze and fix your problem.

  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.




We will have to work outside windows to try to fix your problem:




Please download Farbar Recovery Scan Tool and save it to a flash drive.
  • Plug the flashdrive into the infected PC.
  • Restart your computer and tap F8 to bring up the Advanced Menu, then click Repair your computer
  • Follow the prompt to enter keyboard input method, and then the prompt to enter a password. If the machine does not have a password, simply click Enter.
  • In the Choose Recovery Tool menu select Command Prompt.
  • You will see a big black window with a blinking cursor (command prompt).

    Access the notepad and identify your USB drive

    In the Command Prompt please type in:
    Code:
    notepad
    and press Enter.
  • When the notepad opens, go to File menu.
  • Select Open.
  • Go to Computer and search there for your USB drive letter.
  • Note down the letter and close the notepad.

    Scan with Farbar Recovery Scan Tool

    Once back in the command prompt window, please do the following:
  • Type in e:\frst.exe and press Enter.
    You need to replace e with the letter of your USB drive taken from notepad!
  • FRST will start to run. Give him a minute or so to load itself.
  • Click Yes to Disclaimer.
  • In the main console, please click Scan and wait.
  • When finished it will produce a logfile named FRST.txt in the root of your pendrive and display it. Close that logfile.

    Transfer it to your clean machine and include it in your next reply.

Very good. This was only the diagnostic, I know where your problem lies. I just need one more diagnostic before fixing your problem:


FRST.gif
FRST search

Once again we shall use FRST for additional checks. Re-run FRST/FRST64 the same way:
  • Copy winlogon.exe;User32.dll into the Search: field in FRST then click the Search Files button.
  • FRST will search your computer for files and when finished it will produce a log Search.txt in the same directory the tool is run.
  • Please attach it to your reply.

Download attached fixlist.txt and save it to your USB flashdrive as fixlist.txt

>> Boot into Recovery Environment


Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens ....
  • Press the Fix button once and wait.
  • FRST will process fixlist.txt
  • When finished, it will produce a log fixlog.txt on your USB flashdrive.


>> Exit out of Recovery Environment and post me the log please.



Try to boot Windows normally...

The Importance of Software Updating:

In order to stay protected it is
very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.

Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.




Recommended additional software:
icon_arrow.gif
TFC - to clean unneeded temporary files.
icon_arrow.gif
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gif
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gif
McShield - to prevent infections spread by removable media.
icon_arrow.gif
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gif
FiheHippo.com Update Checker - to keep your programs up-to-date.
icon_arrow.gif
Adblock - to surf the web without annoying ads!



Post-cleanup procedures:


Download DelFix by Xplode and save it to your desktop.
  • Run the tool by right click on the
    51a5ce45263de-delfix.png
    icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)
The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
