When I log into Tesco, it will not load and says, your browser(firefox) has failed security checks. I am using Norton 360 and run a full scan with no indications. All other apps and icons load using Firefox. Tesco refuses to. I have removed it and re-loaded it several time. I worked well untill yesterday when I did some routine windows updates.
