I've never turned it on. The confusing thing is that it's not always showing up, or not showing up. I'm not seeing any rhyme or reason for when it decides to show up in the taskbar. I've had the machine for a couple years now, and it's only been in the past 3-4 months that I even knew this existed. The first time, I shut down, ran a full boot-scan of my anti-virus, followed by M-BAM, because it surprised me that much.
