I keep receiving a site that claims to be "Critical Firefox Update" and offers me a chance to download a file "firefox-patch.js" from https://biadesevismetube.org. Attached is a photo of the page as I see it on my computer. I do not believe this is a legitimate Mozilla update since my browser is up to date. I think it is some type of malware, but it keeps appearing every day as a popup new tab. How can I stop this site from appearing. Norton already makes me aware and does not let it load. Thank you. sgpast
