Operating System
Windows 7
Infection date and initial symptoms
Around December 19th. 100% CPU usage for no reason
Current issues and symptoms
Only while connected to the internet, does this occur. Eventually, DLL replicates as a process and consumes all CPU resources.
Steps taken in order to remove the infection
I have tried AVG and Malwarebytes. They both find things, but do not eliminate it. After some research, I have identified that HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{AB8902B4-09CA-4bb6-B78D-A8F59079A8D45} is present. I cannot remove it.

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.

Hi Twin Eagle.
Last night, I read that I might have Poweliks. I ran ESET. I no longer see DLL host replication. But, the registry was still wrong. I include the FRST logs from immediately after ESET ran, as well as the ESET log. Then, as you suggested I ran downloaded and ran MBAR root kit. It found 4 registry errors and cleaned them. I have included the logs from MBAR. And, I re-ran FRST and include these logs as well.
Please advise what to do next. I will make no other changes until you advise me.
Chuck

Uninstall CCleaner Packages




Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on
    icon and select
    Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Running sweet! There is still a registry key as described at the beginning. Maybe this is a not a problem after all?
Also, I notice that there is a user "Updatus" or something like this. I did not intentionally create this user. Is it legitimate? I do not see it in the normal user management tools within windows.
Again, machine runs like new. No more replicant Dll processes and lightning fast operation.
How do I donate?
