I'm new and not sure if this is the right place to put this note. Two times in the last week while reading emails in Yahoo mail on a laptop, mail screen changes to a screen showing a message URGENT CHROME UPDATE (or something very similar). I closed the tab and reopened Yahoo mail and all is fine. I did run Norton Security full disk and found nothing and also ran Malwarebytes and it didn't find anything either. Is there something on the computer making this screen come up or perhaps its in an email that is "normal" and recognizable?
