Obnoxious Scareware tab reopens on start. How to start without unwanted tab and only home tab

Posted

Accidentally got to “scareware” tab that refuses to close, flashing light, siren and voice insisting my pc should not be shutdown on pain of losing data. Trying to compel calling a “Microsoft Engineer “ at 1-844-387-0777 and or entering user name and password.

I regain control by ending process in program manager (Ctrl-alt-delete) but restarting Firefox brings me back to obnoxious tab again. Norton scan shows pc (running windows 7) is not infected with anything known. Other browser (chrome) works fine.

You are likely seeing this because the tab is being restored each time you open Firefox.

I'd do the following:

You are likely seeing this because the tab is being restored each time you open Firefox. I'd do the following: * Download Malwarebytes, from www.malwarebytes.com and run a full scan. * Start Firefox in Safe mode by holding down the shift key, and see if you can close the tab. * If you can't, then refresh Firefox. [[Refresh Firefox - reset add-ons and settings]] * Finally, install uBlock Origin to prevent this from happening again, https://addons.mozilla.org/firefox/addon/ublock-origin/

Thanks for the quick response! Malwarebytes found nothing. Starting in safe mode did the trick.
