I've gotten a couple of screens pop up telling me to download a "Mandatory Update" to Java. Has the right looking logos. But what troubled me is that I CAN'T CLOSE THAT PAGE. I can minimize it and keep working but can't close it. When I try to close, it gets into a circular thing where I get a message asking if I want to leave the page, and if I say "Yes" it just comes back with the same screen. So now I'm suspicious...... I have been restarting to get rid of it.
