What is Dotdo-Audio?

The Malwarebytes research team has determined that Dotdo-Audio is a browser hijacker. These so-called "hijackers" alter your startpage or searchscopes so that the effected browser visits their site or one of their choice.
This one uses a "man in the middle" method on Chrome and Firefox. It also uses audio advertisements.

How do I know if my computer is affected by Dotdo-Audio?
  • Your computer will slow down considerably.
  • You may hear audio advertisements even when there are no browser windows open.
  • You may notice hidden and renamed files in the Chrome and Firefox application folders.
    The renamed and hidden files are the original browser executables.
  • You may have seen a few command prompts during install:

    Using taskkill to shut down Chrome and Firefox processes, so it can replace them.

    And you may find a few Scheduled Tasks similar to these:


    How did Dotdo-Audio get on my computer?

    Browser hijackers use different methods for distributing themselves. This particular one was installed by a trojan.

    How do I remove Dotdo-Audio?

    Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.
    • Please download Malwarebytes Anti-Malware to your desktop.
    • Double-click mbam-setup-{version}.exe and follow the prompts to install the program.
    • At the end, be sure a check-mark is placed next to:
      Launch Malwarebytes Anti-Malware
    • Then click Finish.
    • Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
    • If an update is available, it will be implemented before the rest of the scanning procedure.
    • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
    • Restart your computer when prompted to do so.
    Is there anything else I need to do to get rid of Dotdo-Audio?
    • No, Malwarebytes' Anti-Malware removes Dotdo-Audio completely.
    • This PUP creates some scheduled tasks. You can read here how to check for and, if necessary, remove Scheduled Tasks.
    • This PUP disables the Windows Defender service. You may want to run services.msc to open Services Manager. Ensure that the Windows Defender service is started and set to Automatic.
    How would the full version of Malwarebytes Anti-Malware help protect me?

    We hope our application and this guide have helped you eradicate this hijacker.

    As you can see below the full version of Malwarebytes Anti-Malware would have protected you against the Dotdo-Audio hijacker. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.


    It also stops some of the outgoing connections the adware tries to make:
