Hey, I just wanted to write to say that Norton Power Eraser is fantastic! I had a perfectly good version of McAfee on my 3 month old Lenovo laptop, and it could not even detect the "Security Shield" malware. It had become incredibly obtrusive, popping up every 30 or 60 seconds to try to force me to pay for some "security software." But I knew where to get real security software and downloaded Norton Power Eraser last night. It took about three tries but, finally, I was able to get the whole thing wiped out. You've made a fan out of me! Thanks Norton!
