What is Weather Forecast Alerts?

The Malwarebytes research team has determined that Weather Forecast Alerts is a browser hijacker. These so-called "hijackers" 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.
Weather Forecast Alerts is a member of the Spigot family as described in the blogpost Spigot browser hijackers.

How do I know if my computer is affected by Weather Forecast Alerts?

You may see these browser extensions/add-ons:

and this altered default search provider:

these warnings during install:

and this new startpage in the affected browser(s):

How did Weather Forecast Alerts get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from their site.

How do I remove Weather Forecast Alerts?

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 Weather Forecast Alerts?
  • If you are using Chrome, you may have to remove the Extension manually under Settings > More Tools > Extensions. Remove the checkmark and click on the bin behind the Weather Forecast Alerts entry.
  • 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 would have protected you against the Weather Forecast Alerts hijacker. It would have warned you before the hijacker could install itself, giving you a chance to stop it before it became too late.

and it blocks traffic to some of their domains:
