How do I remove Page update?

Our program Malwarebytes can detect and remove this potentially unwanted program.

• Please download Malwarebytes to your desktop.
• Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
• Then click Finish.
• Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
• If another update of the definitions 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 Page update?

• No, Malwarebytes removes Page update 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 Malwarebytes browser extension would have protected you against the Page update hijacker. It would have blocked their domain, giving you a chance to stop before it became too late.
