SPY SHERIFF "Your computer is infected! Windows has detected spyware infection." I'm getting this message along with a blinking red X in the bottom right of my screen. I don't know how it happened. One day my computer was fine, the next day I have this red x and something called "spy sheriff" was mysteriously installed on my computer. I removed "spy sheriff" and my computer functions normally. . .except I have that red x and the constant popups saying "windows has detected spyware infection." I did have a spyware/adware problem a month or two ago, but I had it gotten rid of. Now, after my computer was totally fine for a while, I have this red x and constant annoying pop ups from it. Also, I notice that this red x and it's pop-ups ONLY appear when I launch Mozilla Firefox internet browser. I've uninstalled and reinstalled Mozilla, but the red x has remained. How do I get rid of it? Thanks!
