What is Access Gov Docs Tab?

The Malwarebytes research team has determined that Access Gov Docs Tab 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.
This particular one is a newtab hijacker and uses web push notifications.

How did Access Gov Docs Tab 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 Access Gov Docs Tab?

Our program Malwarebytes can detect and remove this potentially unwanted program.
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 Access Gov Docs Tab?
  • No, Malwarebytes' Anti-Malware removes Access Gov Docs Tab completely.
  • If you have allowed the notifications you can read here how to disable them.
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 Browser Guard, would have protected you against the Access Gov Docs Tab hijacker. It blocks their domains:
