The qvo6.com adware is a browser hijacker that is bundled with certain free programs that you can download off of the Internet. This adware is considered a browser hijacker because it changes your web browser's home page and default search provider to qvo6.com without your permission. It also states on installation that you will be able uninstall this program via your Uninstall Programs or Add or Remove Programs control panel, when in reality you are unable to do so. This makes it so you are required to use specialized tools to remove it. Furthermore, this adware will append the argument http://www.qvo6.com/?utm_source=b&utm_medium=mlv&from=mlv&uid=<hard drive id>&ts=<timestamp> to various web browser shortcuts and sometimes non-internet related programs. This causes the qvo6.com web page to open when you launch one of these hijacked shortcuts.

Automated Removal Instructions for Qvo6.com using AdwCleaner, and Shortcut Cleaner:

 

  1. This removal process may appear overwhelming due to the amount of the steps and the various programs used. Please do not be concerned as it is only written this way to give you clear and easy instructions so that anyone can use this guide. Before using this guide, you should print out these instructions and close any open programs and files as your web browser will need to be closed and your computer rebooted later in this fix.

  2. Before we do anything we first want to download Rkill in order to terminate any programs that may interfere with the removal process. 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.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    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.

  3. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Qvo6.com 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.


  4. When Rkill has finished, you now need to 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:

    http://www.bleepingcomputer.com/download/adwcleaner/

  5. 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 its start screen as shown below. If Windows prompts you as to whether or not you wish to run AdwCleaner, please allow it to run.


    AdwCleaner Start Screen

  6. 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 most people, the contents of the Results section may appear confusing or as gibberish. Unless you see a program name that you know should not be removed, please continue with the next step.

  7. 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 reboot the computer. Please do so 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.



    AdwCleaner Reboot Prompt

    Please click on the OK button to let AdwCleaner reboot your computer.

  8. 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.

    Please review this log file and then close the Notepad Window.

  9. Unfortunately, Qvo6.com also hijacks your web browser shortcuts so that the Qvo6.com home page will open when you start your web browser in a certain way. To fix these shortcuts you need to use a program called Shortcut Cleaner. Please download and save Shortcut Cleaner to your desktop using the following link:

    http://www.bleepingcomputer.com/download/shortcut-cleaner/

  10. Once the program has been downloaded, please double-click on the sc-cleaner.exe icon that will now be on your desktop. If Windows prompts you as to whether or not you wish to run Shortcut Cleaner, please allow it to run. Once the program starts, it will scan your computer for hijacked shortcuts and clean them. When it has finished it will display a log file that contains a list of all Windows shortcuts that were hijacked and disinfected.

    After reviewing this log file, please close the Notepad window.

 

Your computer should now be free of the Qvo6 Browser Hijacker program.
