Hi - I'm unable to load Firefox because the home screen is hijacked. I've run the free Malwarebytes and it finds nothing. I've used CCleaner as well. I've loaded a print screen. Any help will be much appreciated.

Hi Doug, to cancel the authentication dialog, try tapping the Esc key several times quickly to break the reload cycle. After that, you should be able to close the tab using Ctrl+w, or press Alt+Home to navigate to your home page. Does that work in this case?

A way out of a trap page is to (force it if needed) Close Firefox. Wait about 20 seconds for Firefox to finish closing. Right-click on the Firefox icon and select Open New Window. +++++++++++++++++++++++++++++++++ Sometimes this works. If it opens, close it by Menu > File > Exit. This will flush out that web page from the Session Store.

Hi to everyone who sent a solution. It seems that the first time I ran CCleaner and Malwarebytes, that nothing changed. I don't know what changed, but while the browser was up with the message "YOUR COMPUTER HAS BEEN BLOCKED" I ran CCleaner and Malwarebytes again and then used the Task Manager to kill Firefox. Then when I ran Firefox again, it ran without problem.
