What is DownloadManagerNow?

The Malwarebytes research team has determined that DownloadManagerNow is a browser NewTab. These so-called "NewTabs" can manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice.

How do I know if my computer is affected by DownloadManagerNow?

You may see this browser extension:

these warnings during install:

warning2.png

You may see this icon in your browsers menu-bar:

this new startpage:

and this new setting:

How did DownloadManagerNow get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from the webstore:

after a redirect from their website:

How do I remove DownloadManagerNow?

Our program Malwarebytes can detect and remove this potentially unwanted program.
[Mindspark only]You can use their own uninstall instructions first, but I would advise to follow the steps below anyway.
  • Please download Malwarebytes for Windows to your desktop.
  • Double-click MBSetup.exe and follow the prompts to install the program.
  • When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
  • Click on the Get started button.
  • Click Scan to start a Threat Scan.
  • When the scan is finished click Quarantine to remove the found threats.
  • Reboot the system if prompted to complete the removal process.
Is there anything else I need to do to get rid of DownloadManagerNow?
  • No, Malwarebytes' Anti-Malware removes DownloadManagerNow completely.
  • If your browsers have been hijacked, you should read our Restore Browser page. You can read there how to fix additional browser redirect methods.
How would the full version of Malwarebytes 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, as well as Malwarebytes Browser Guard, would have protected you against the DownloadManagerNow hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
