Hi there,

I'm not sure if this is a Windows update related problem but since Friday I can't open any internet browser other than Edge on my laptop. I'm using Windows 10. After double clicking to open the browser, nothing happens. There's no error messages other an in Event reader saying there's a fault.

I was told to reset my laptop which I did. It hasn't solved the problem and my desktop settings aren't quite right like the search bar on Start.

I've tried running Malware programmes, run a full antivirus scan etc but nothing works! HELP!

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}
