Whenever I launch chrome, it runs these random weird processes that say they are being run by google chrome but are not. Whenever I close google chrome, they are still there and are hogging HUGE resources. My computer is stuttering and having trouble running. I open the file location, and its in this weird named folder. I can't delete them, but i deleted the folder in safe mode and it worked for a couple of seconds. When I opened up chrome in normal mode, the malware came back just like before...

I attempted to replace the infected rundll32.exe in the system32 folder with a clean stock rundll32.exe i found online, but it has mad the problem much worse now. Now my system is opening up hundreds of rundll32.exe's instead of the one before. And now my computer is stuttering and struggling to run. I'm very scared and really need to get rid of this malware. Also it displayed an error message saying that it can't find a certain dll starting with an n. I closed out of the error message and cant remember the name of it now.

I need your guy's help and have been up for hours trying to amend the problem. Thank you for reading, I hope i can fix this issue without having to wipe my computer clean.

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
    fjqb1h.png
    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.

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:

TFC - to clean unneeded temporary files.

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.

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.
