Any other scammer information: one of my clients kept getting these fake virus alerts so I logged in to her computer and discovered that she had been googling Amazon and clicked on the ‘sponsored link’ which opens up this fake alert. Ad is by Lumon LLC. I reported it to google but ad is still running.
