Help with multiple dllhost.exe *32 running please

Recommended Posts

Like so many others I see, I have been struggling with the issue of something causing multiple dllhost.exe processes to start and run until my laptop CPU and memory are at 100% utilization.


I have been reading a lot of the related posts on this subject and it seems that while this issue is pervasive; each system requires it's own unique fix or repair.


I have been able to stop the process with RogueKiller; however I am confident that as soon as I have to restart my laptop it will all start again.


I am using a Dell Latitude E6520 running 64-bit on Windows 7 Pro SP1. I have repeatedly updated and ran MBam V2.0.3.1025 with no threats found; I also downloaded and ran Mbar I had Trend Micro and Windows Defender; out of frustration; I added Avast 2015 and turned off the other two. Again nothing is found.


I would appreciate any assistance offered.

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

  • Important: To help me reviewing your logs, please post them in code boxes. You can create them by clicking on the <>-symbol on top of the reply window.




Scan with Gmer rootkit scanner

Please download Gmer from here by clicking on the "Download EXE" Button.

  • Double click on the randomly named GMER.exe. If asked to allow gmer.sys driver to load, please consent.
  • If it gives you a warning about rootkit activity and asks if you want to run scan...click on NO.
  • In the right panel, you will see several boxes that have been checked. Uncheck the following ...
    • Sections
    • IAT/EAT
    • Show All ( should be unchecked by default )

    [*]Leave everything else as it is. [*]Close all other running programs as well as your Browser. [*]Click the Scan button & wait for it to finish. [*]Once done click on the Save.. button, and in the File name area, type in "ark.txt" or it will save as a .log file which cannot be uploaded to your post. [*]Save it where you can easily find it, such as your desktop. [*]Please post the content of the ark.txt here.

Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries

Scan with TDSS-Killer

Please read and follow these instructions carefully. We do not want it to fix anything yet (if found), we need to see a report first.

Download TDSSKiller.zip and extract to your desktop

  • Execute TDSSKiller.exe by doubleclicking on it.
  • Press Start Scan
  • If Malicious objects are found, do NOT select Copy to quarantine. Change the action to Skip, and save the log.
  • Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt

Please attach this file to your next reply.

Hello Marius,


My laptop flashed a blue screen about 4 minutes after I posted my reply that said something about new software and then immediately shut down.

I have restarted in safe mode with networking.

I do not know why this happened or what caused it; but I thought I should let you know.


Thanks again for your Help,

Hello Marius,


I am very grateful for your assistance. It appears to me that you have guided me to a successful removal of the malicious process.


The only way that I knew when the malicious process was happening was to watch Windows Task Manager. Previously I would see dllhost.exe *32 processes running and then they would start multiplying. Now I occasionally see dllhost.exe run; then disappear. 

I have not seen any dllhost.exe *32 processes running for a few days.


I have avoided any financial sites or online transactions since I first noticed the Dllhost.exe *32 behavior. When do you think it will be safe for me to use online credit card or paypal transactions? I would like to upgrade from Mbam free to premium and I would also like to buy you a beer or two as well.


Again; I thank you for your help and support.

I was able to run the Security check after reboot and have attached the log.

I tried to copy and paste; but it would not paste for some reason.

I am puzzled about the "Java version out of date" statement on the log. I have gone to start - all programs - Java - check for updates - update now: I get "you already have the latest Java platform on this system"


As always, thank you for your help.

Recommendations: How to protect yourself

  • System Updates
    Please ensure to have automatic updates activated in your control panel.
    For further information and a tutorial, see this Microsoft Support article.
  • Protection
    What you need is one (not more) virus scanner with background protection. Additionally I recommend a special malware scanner to run on demand weekly.
    Personally I am using avast! Antivirus Free Edition and Malwarebytes Anti-Malware. They offer good protection for free.
    • To keep your browser free of advertising, you may install the Adblock Plus browser extension.
      It will filter unwanted advertising out of the website´s content.
    • To protect yourself from accidentally visiting malicious web sites, install the Web of Trust (WOT) browser extension.
      It will display a green (safe), yellow (unknown) or red (potentially dangerous) icon for a visited website within your browser.
      In addition, before accessing a dangerous classified web site, a warning screen is displayed.

    [*]Up to date Software
    Keep your Windows and your third party software up to date. The easiest way to get infected is an outdated windows, followed by: browser(s) (including add-ons and plug-ins), Adobe Flash Player and Adobe Reader, Java Runtime Environment, your antivirus program and so on. These links may help you to check:

    Hardware issues, malware, fire, lightning strike: There is a long list of different ways to loose all your data. Back up your files regularly. Use the windows internal backup function or a third party tool and save your data onto an external hard drive, cloud storage, optical media like CDs or DVDs or (if available) a professional network backup system. [*]Behaviour
    The commonest error when using a computer is "error 80" - what means that the error is located about 80cm in front of the monitor. This is a common joke between IT support technicians but it shows that all the safety mechanisms won´t help if you aren´t careful enough.

    • While surfing the internet, don´t click on anything you don´t know. In the worst case, it infects your system with malware.
    • Watch your step in social networks! Many cyber criminals use them to spread malware, mine personal pata (to be sold to advertising companies, for example) or simply do damage to other users. Even if a received hyperlink within a message seems to be coming from one of your friends, have a closer look. In addition, don´t click everything.
    • When installing software, have a look to each of the setup windows and uncheck any additional toolbars or free programs that may be offered additionally. Most of today´s setup procedures contain potentially unwanted programs so keep them off your system.
    • Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
      They are a security risk which can make your computer susceptible to a wide variety of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.

Here in the States we just celebrated the Thanksgiving Holiday, a national day of giving thanks for our many blessings.

So in that spirit; I share that I am thankful for Psychotic  (Marius) and all of the other advisers here on the forum.

Without you good people; many of us would remain victims of the malicious horde.

I believe I speak for many people all over the world when I say thank you to all of the advisers.
