Husband's computer windows 8.1 has a horrible adware cloudScout that pops up everywhere. Even on the Norton site when trying to do this on my own. We have Norton 360 and ran scan - showed nothing. Then tried Norton Power Eraser - nothing. The computer is slower then when new (bought Christmas 2014), freezes and hangs. He only uses to search R/C Airplanes. Can this be fixed? Was going to go on line for tech support but not use to Windows 8.1 and no need to frustrate technician with my ignorance. Would be nice to turn computer over and then technician handle it. Told hubby don't open anymore pop-ups. Here is hoping for the best.
