What is UP Tab?
The Malwarebytes research team has determined that UP 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.
How do I know if my computer is affected by UP Tab?

How do I remove UP 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 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.
- No, Malwarebytes' Anti-Malware removes UP Tab 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.
We hope our application and this guide have helped you eradicate this hijacker.
As you can see below the full version of Malwarebytes would have protected you against the UP Tab hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
