MALWARE - MULTIPLE dllhost.exe*32


Recommended Posts

Hey Malwarebytes,



My issue started with     http://gameharbor.org/  opeing on firefox by it self everytime


when I turned on my computer. It did NOT make computer slow but it bothered me enough


so with some googling I was able to  fix the problem and new one surfaces.  I downloaded


and gave try on 'Malwarebytes' and cought couple dozens of malicious files but problem


still persists. Symtom is similar to many other folks here, dllhost.exe*32 keeps popping up


slowing the comp.  Slowdown starts within 10minutes of starting computer and slows


download speed also.  Will be waiting for further instructions.


Please help me beat these suckers away!!

General P2P/Piracy Notice: 

If you are using Peer to Peer (P2P) filesharing software such as uTorrent, BitTorrent or similar you must either fully uninstall or completely disable the programme(s) from running whilst receiving assistance at this forum. 
Failure to remove or disable such software will result in your topic being closed and no further assistance being provided.
If you have illegal/cracked/keygen or similar software on the computer, please remove/uninstall the software now and read the policy on Piracy. Failure to do so will also result in your topic being closed.


Please read through the points below to ensure this process moves as quickly and efficiently as possible.

  • Please read through my instructions thoroughly, and ensure you carry out each step in the order specified.
  • Please do not post logs using the CODEQUOTE or ATTACHMENT format. Logs should be posted directly in plain text. If you receive an error whilst posting, please break the log in half and use multiple posts.
  • Please do not run any tools or take any steps other than those I provide for you. Independent efforts may make matters worse, and will affect my ability in ascertaining the current situation & providing the best set of instructions for you.
  • Please backup important documents before proceeding with my instructions.
  • If you come across any issues whilst following my instructions, please stop and inform me of the issue in as much detail as possible. Please do not hesitate to ask before you run anything.

  • Ensure you are following this topic. Click xetYzdbu.png.pagespeed.ic.U7AjmRUewW.png at the top of the page.

Unfortunately, your computer is infected with a rootkit. As such, I must issue the following warning. Please let me know how you wish to proceed. 



One or more of the identified infections is known to use a backdoor, that allows attackers to remotely control your computer, download/execute files and steal critical system, financial and personal information.

Please disconnect your computer from the internet immediately. If your computer was used for online banking, has credit card information or other sensitive data,using a non-infected computer/device you should immediately change all account information (including those used for banking, email, eBay, paypal, online forums, etc). Consider these accounts already compromised.

If you have used a router, you will need to reset it with a strong logon/password to ensure the malware cannot gain control before connecting again. Banking and credit card institutions should be notified of the possible security breach immediately. Please read the following for more information: How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Whilst the identified infection(s) can be removed, there is no way to guarantee that your computer will be trustworthy again. This is due to the nature of the infection, which allows the attacker complete control over the computer. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat the hard drive and reinstall the Operating System. Please read the following articles for more information.

Please let me know how you wish to proceed, and if you have any questions.

Hi there Adam,


I'm Ryan, Thanks for taking a look at the problem.  For the best of my information protection I will be formating computer. This sounds more reasonable and less risky.

I do have another question for you thogh, I have been getting by only using Free AVG /adblock and windows firewalls for good 4~5 years before my last format.

Are there any software you recommend for additional protection to prevent rootkit such as this one infecting my computer?

Hello Ryan, 


I am not an advocate of AVG. 

  • The programme is a resource hog.
  • In 2010, AVG partnered with Limewire - a P2P filesharing programme. P2P filesharing is one of largest infection vectors.
  • AVG bundles registry/optimization software. Programmes that purport to clean your registry are snake oil. 
  • AVG bundles AVG Secure Search; software considered as a browser hijacker. 
  • I have seen many complaints concerning the quality of customer support. 


I recommend one of the following anti-virus software. 

For a paid solution, my choice of anti-virus is ESET NOD32, and for a free solution, my choice of anti-virus is avast!. However, there is no universal "one size fits all" solution that works for everyone and there is no single best anti-virus. What works for me may not work for you and your machine. 


I have compiled below a list of resources you may find useful. The articles document information on computer security, common infection vectors and how you can stay safe on the Internet.

The following programmes come highly recommended in the security community.

  • xKsUqI5A.png.pagespeed.ic.vn1Hlvqi8h.jpg AdBlock is a browser add-on that blocks annoying banners, pop-ups and video ads.
  • x7D2ig3K.png.pagespeed.ic.x4TC1AK8OX.jpg Emsisoft Antimalware (free) acts as an additional on-demand scanner, and can be used in conjunction with your Anti-Virus. 
  • EG85Vjt.png Malwarebytes Anti-Exploit (MBAE) is designed to prevent zero-day malware from exploiting vulnerable software.
  • x6YRrgUC.png.pagespeed.ic.HjgFxjvw2Z.jpg Malwarebytes Anti-Malware Premium (MBAM) incorporates real-time protection and is designed to run alongside your Anti-Virus. 
  • xjv4nhMJ.png.pagespeed.ic.A5YbWn1eDO.png NoScript is a Firefox add-on that blocks the actions of malicious scripts by using whitelisting and other technology. 
  • 3O8r9Uq.png Sandboxie isolates programmes of your choice, preventing files from writing to your HDD unless you approve the file. 
  • DgW1XL2.png.pagespeed.ce.v1OlJl_ZAS.png Secuina PSI will scan your computer for vulnerable software that is outdatedand automatically find the latest update for you.
  • xj1OLIec.png.pagespeed.ic.k6hhwopU0q.jpg SpywareBlaster is a form of passive protection, designed to block the actions of malicious websites and tracking cookies.
  • xsHjS79L.png.pagespeed.ic.n4Sk8_GzZn.jpg Unchecky automatically removes checkmarks for additional software in programme installers, helping you avoid adware and PUPs. 
  • xJEP5iWI.png.pagespeed.ic.4tmM1lM7DQ.png Web of Trust (WOT) is a browser add-on designed to alert the user before interacting with a potentially malicious website. 


To help combat this particular infection (Poweliks), I recommend looking into using WinPatrol.
