Winvmx Client is a potentially unwanted program, or PUP, that is bundled with other software that you download from the Internet. When Winvmx is installed, it will run in the background and constantly connect to various sites on the Internet. When it connects to these sites it will watch videos and render advertisements, but it is all done in a hidden window that is not displayed to the owner of the computer. It is unknown why this program exhibits this behavior, but it could be to generate ad revenue or as a search engine optimization tactic.
Below you can see the constant connections made by Winvmx.
It does this by installing a customized version of Chrome that does not display the normal browser window. This allows it to perform this activity without the knowledge of the user. Furthermore, since it does not create any Start Menu shortcuts or Desktop icons, the only way you would know that something is wrong is based on the following symptoms.
- The computer may become sluggish.
- The computer's CPU utilization may be much higher than normal.
- You may find processes called vmxclient.exe or svcvmx.exe running in Task Manager. These processes will have a description called Winvmx Client (32-bit).
- Applications and Windows may freeze.
- Your Internet may become slower due to the hijacked bandwidth that this application uses.
- When you try to end the vmxclient.exe or svcmx.exe processes in Task Manager, you will receive an error stating "Unable to Terminate Process The operation could not be completed. Access is denied."
- When you try and run security software, such as anti-virus or anti-malware programs, the programs will not load and an alert stating "The Requested Resource is in Use" is displayed.
How did the Winvmx Client get on my computer?
It is important to note that Winvmx is installed by other programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you cancel the install and not use the free software.
As you can see, the Winvmx PUP is a program that provides no apparent benefit to the user, but consumes resources that could be used for other legitimate programs. Therefore, if you find that this program is causing problems on your computer, you can use the removal guide below to remove the Winvmx Client for free.

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.
This infection is constantly changing in order to bypass our methods of removing it. If you encounter any issues with the steps below, just skip those sections and continue to the next appropriate step. Also please report the issue you had by creating a new topic in the Am I Infected forum with details as to what happened.
At this point you should download Malwarebytes Anti-Rookit, or MBAR, to scan your computer for rootkits. Please download Malwarebytes Anti-Rootkit from the following location and save it to your desktop. When downloading MBAR, make sure you use the download link that is labeled Version 188.8.131.523:
Once downloaded, close all programs and Windows on your computer, including this one.
Double-click on the Malwarebytes Anti-Rootkit icon that you just downloaded. This will start the installation of MBAR onto your computer. If you see a warning, like the one below, please click on the Yes button to continue.
You will now be prompted for the directory that you wish to install MBAR into as shown below.
At this prompt press the OK button to allow it to extract the files into a mbar folder on your desktop.
MBAR will now automatically start and you will be presented with the introduction screen.
At this page click on the Next button and you will be at the Update screen.
At the Update screen, click on the Update button.
When it has finished updating and has stated that the databases are up-to-date or have been updated, click on the Next button.
You will now be at the scan screen as shown below.
To begin scanning for the installed rootkit, click on the Scan button and the scan will begin.
Please be patient while Malwarebytes Anti-Rootkit scans your computer for rootkits as this process may take some time.
If you see that the Malwarebytes Anti-Rootkit appears to be frozen, or displays "Not Responding", do not be concerned and just let it continue. It is just analyzing a large file and will continue when done.
When MBAR has finished scanning your computer, it will display a scan summary as shown below.
After reviewing the scan results, click on the Cleanup button. MBAR will now create a System Restore Point and begin to remove any detected rootkits and infections. During this process MBAR will most likely ask you to reboot your computer. When you receive this prompt, please reboot your computer.
When the computer reboots, you can login again and continue with the rest of the steps in this guide.
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.
For this particular malware, we need to download the unsigned version of Rkill. When at the download page, be sure to only click on the Download Now button labeled Rkill Unsigned. When you are prompted where to save it, please save it on your desktop.
Once it is downloaded, right-click on it and select rename. Then give it a random name. Now double-click on this renamed version of RKill to automatically attempt to stop any processes associated with Winvmx Client 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.
Do not reboot your computer after running RKill as the malware programs will start again.
If Rkill is blocked from running, please proceed to the next step.
At this point you should download Zemana AntiMalware, or ZAM, in order to scan your computer for any any infections or adware that may be present.
As this infection will prevent the normal Zemana executable from running, we have renamed it to eXplorer.exe so that it can be executed.
Please download Zemana AntiMalware from the following location and save it to your desktop:
Once downloaded, close all programs and open windows on your computer.
Now double-click on the icon on your desktop named eXplorer.exe. This will start the installation of Zemana AntiMalware onto your computer.
When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, Zemana will automatically start and display the main screen.
If Zemana did not automatically start then that means the infection blocked it by its name. To resolve this we need to open the C:\Program Files (x86)\Zemana AntiMalware folder and then rename the ZAM.exe executable.
Once the folder is open, click once on the ZAM.exe file to select it, and then click on the F2 button on your keyboard. This will enter rename mode where you can change the name of the file. If the ZAM file appears to be named just ZAM, rename it to iexplore. If it is named ZAM.exe, then rename it to iexplore.exe.
Once the file has been renamed, double-click on the file to execute it. Zemana Anti-Malware should now start.
You will now be at the main screen for Zemana AntiMalware as shown below.
Above the Scan button, please change the scan type to Deep Scan and then click on the Scan button to start the malware removal scan.
Zemana AntiMalware will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.
When Zemana has finished finished scanning it will display a screen that displays any malware that has been detected. Please note that the infections found may be different than what is shown in the image below.
Review the scan results and when you are ready to continue with the cleanup process, click on the Next button to delete or repair all of the the selected results. Once you click on the Next button, Zemana will remove any unwanted files and fix any modified legitimate files. If you receive a warning that Zemana needs to close your open browsers, please close any web browsers that may be open and then click on the OK button to continue.
Zemana will now create a System Restore Point and remove the detected files and repair any files that were modified.
When the process is complete, you will be shown a screen that says Completed. At this screen, you can now close the Zemana AntiMalware screen and continue with the rest of the instructions. If Zemana requests that you reboot the computer, please do so, and then continue with the next step.
At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any infections, adware, or potentially unwanted programs that may be present. Please download Malwarebytes from the following location and save it to your desktop:
Once downloaded, close all programs and Windows on your computer, including this one.
Double-click on the icon on your desktop named mb3-setup-1878.1878-184.108.40.2063.exe. This will start the installation of MBAM onto your computer.
When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.
MBAM will now start and you will be at the main screen as shown below.
We now need to enable rootkit scanning to detect the largest amount of malware and unwanted programs that is possible with MalwareBytes. To do this, click on the Settings button on the left side of the screen and you will be brought to the general settings section.
Now click on the Protection tab at the top of the screen. You will now be shown the settings MalwareBytes will use when scanning your computer.
At this screen, please enable the Scan for rootkits setting by clicking on the toggle switch so it turns green.
Now that you have enabled rootkit scanning, click on the Scan button to go to the scan screen.
Make sure Threat Scan is selected and then click on the Start Scan button. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.
When MBAM is finished scanning it will display a screen that displays any malware, adware, or potentially unwanted programs that it has detected. Please note that the items found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.
You should now click on the Remove Selected button to remove all the selected items. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
You can now exit the MBAM program.
Now please download AdwCleaner and save it to your desktop. AdwCleaner will scan your computer for adware programs that may have been installed on your computer without your knowledge. You can download AdwCleaner from the following URL:
When AdwCleaner has finished downloading, please double-click on the AdwCleaner.exe icon that now appears on your desktop. Once you double-click on the icon the AdwCleaner program will open and you will be presented with the program's license agreement. After you read it, click on the I agree button if you wish to continue. Otherwise, click on the I disagree button to close the program. If Windows prompts you as to whether or not you wish to run AdwCleaner, please allow it to run.
If you selected to continue, you will be presented with the start screen as shown below.
Now click on the Scan button in AdwCleaner. The program will now start to search for known adware programs that may be installed on your computer. When it has finished it will display all of the items it has found in Results section of the screen above. Please look through the results and try to determine if the programs that are listed contain ones that you do not want installed. If you find programs that you need to keep, then uncheck the entries associated with them.
For many people, the contents of the Results section may appear confusing. Unless you see a program name that you know should not be removed,please continue with the next step.
To remove the adware programs that were detected in the previous step, please click on the Clean button on the AdwCleaner screen. AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.
Please save your work and then click on the OK button. AdwCleaner will now delete all detected adware from your computer. When it is done it will display an alert that explains what PUPs (Potentially Unwanted Programs) and Adware are. Please read through this information and then press the OK button. You will now be presented with an alert that states AdwCleaner needs to reboot your computer.
Please click on the OK button to let AdwCleaner reboot your computer.
When your computer reboots and you are logged in, AdwCleaner will automatically open a log file that contains the files, registry keys, and programs that were removed from your computer.
