I know it's in Windows, because it appears in all three browsers(Firefox,Chrome, and Edge) and in Word, Open Office, etc. It's an ad, but Ad Block Plus, Ad-Aware won't remove it. It just shows up as a band about 4-6" across the bottom of the screen. I can type over it, but it blocks most of what's in back. It basically says Series 5, Hyper Real Engine with a Samsung logo inside. How can I get rid of it? It comes on, stays on for about 15 seconds, disappears for around 15 seconds and the continuous loop never stops. I've tried everything, including anti-virus programs, turning my PC on and off, but no success.
