The reason you are seeing
YOUR DEVICE HAS BEEN BLOCKED advertisements is because of an advertising-supported software infection. These scam adverts will attempt to convince you to call Tech support so that scammers could get remote access to your computer and set up suspicious, expensive programs. If you are dealing with advertising-supported programs , it wouldn't be shocking if the alerts were pretty invasive and appeared over and over again. You might have picked up the adware contamination when you were installing freeware. You just need to not fall for these scams, the warnings are harmless themselves. However, if you did call them, you might be scammed out of a lot of money, or more severe malware may be installed, and that may authorize them access to your personal information.

When you erase YOUR DEVICE HAS BEEN BLOCKED, the advertisements should go away, and your browsing will no longer be interrupted.
