Dear God! Used this ONCE on my work computer and afterwards I started getting 22 ad's a day. That is not an exaggeration. I have to clear out 20 to 25 notifications from mapquest DAILY. Viagra ad's with what looks like a picture of a penis on it pops up. It is actually a finger dipped in vaseline for whatever reason. Fake news about Trump meeting with Hitler or whatever pops up. It never ends! I had to email IT today even after I turned on pop-up blockers to get it off my computer. NEVER AGAIN!
