How to remove the Poweliks Trojan (Removal Guide)

  • December 5, 2014

The Poweliks infection is a Trojan downloader for the Windows operating system that downloads and executes other malware on your computer. This infection is typically installed via exploit kits found on hacked web sites that exploit vulnerabilities on your computer when you visit them. Once the initial installer is executed, the actual Poweliks infection is stored in the Windows registry rather than as a file on your hard drive. The installer then deletes itself. This method of storing the malware files in the Registry rather than the hard drive makes it more difficult for antivirus programs to properly detect it.

While infected, there are symptoms that indicate Poweliks is installed on your computer. These symptoms include:

  • Task Manager will show numerous occurrences of DLLHOST.exe or a file called dllhst3g.exe running as shown in the image below. If you are using a 64-bit version of Windows, then these entries will be listed as dllhost.exe *32 and dllhst3g.exe *32.

  • Pages may be blocked or unreachable while you are browsing the web.

  • Your computer will act sluggish and programs will take a long time to start up.

  • Unusual disk activity.

  • The inability to download files using Internet Explorer. When you attempt to download a file you will receive a message that states Your current security settings do not allow this file to be downloaded. A screen shot of this alert is below.

    No downloads in Internet Explorer

  • Alerts containing PowerShell errors.

If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.

To remove Poweliks, follow these steps:


This removal guide may appear overwhelming due to the amount of the steps and numerous programs that will be used. It was only written this way to provide clear, detailed, and easy to understand instructions that anyone can use to remove this infection for free. Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.


To terminate any programs that may interfere with the removal process we must first download the Rkill program. Rkill will search your computer for active malware infections and attempt to terminate them so that they wont interfere with the removal process. To do this, please download RKill to your desktop from the following link.


When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.


Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Poweliks and other malware. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and a log file will open. Please review the log file and then close so you can continue with the next step. If you have problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.

Do not reboot your computer after running RKill as the malware programs will start again.


Poweliks will change your Internet Explorer security settings so that you are unable to download files with it. To fix this, press the Windows key (Windows Key) on your keyboard, and while holding it down, also press the R key on your keyboard. This will open the Run dialog box as shown below.

Run Dialog

In the Open: field in the Run dialog box, type the text inetcpl.cpl, as shown in the image above, and then press the OK button. Once you press OK, the Internet Properties screen will open.


When the Internet Properties screen is open, click on the Security tab and you will be shown the security settings for Internet Explorer as shown below.

Now click on the Reset all zones to default level button as indicated by the blue arrow in the image above. After you press the reset button, click on the Apply button and then the OK button to save your changes and close the Internet Properties screen.


You can now open Internet Explorer or any other browser and download the ESET Poweliks Cleaner.

Once the ESET Poweliks Cleaner tool has been downloaded, look for the file called ESETPoweliksCleaner.exe on your desktop and double-click it. This will launch the program, which will then display a license agreement. Read through the agreement, and if you agree to it, click on the Agree button to continue.

Press any key on your keyboard and the program will close. If you get warnings from Windows when you close the program about it not running successfully, you can just close the messages and disregard them.


Now restart your company to finalize the removal. When your computer restarts, if you want to review what was removed by the ESET cleaner, you can review the ESETPoweliksCleaner.exe_<timestamp>.log file that will be on your desktop. Timestamp will be replaced by the time and date that you ran the program.


Now that you are back at the desktop, you should scan your computer with an anti-virus program. ESET has a free online scanner that you can use once to detect and delete infections. I suggest you use this to make sure there is no other malware present. The online scanner can be found here:
