How can I block pop up ads from "online advertising support"

I have to say it is refreashing to get answers from a community board on the same day of the question, kudos to you, you are truely most kind

when I go on a site to buy something I get these pop up ads all over the screen, it gets so bad you can not see the original screen of the site. on the ads you can otp out but the minute you change the page page they come righr back. and there is no one to contact the only name you see is "ONLINE ADVERTISING SUPPORT"

Hello Edward. You will receive some advertisement popups if some adware programs installed on your computer unknowingly while you try to install any other programs. You can remove this easily, first go to control panel and click on Programs and Features and in the list of programs search for any tool bar or search bar or any weird programs installed in your computer. If you see some suspicious program just uninstall it. If you don't see any of such programs then please open your browser and you need to delete the unwanted plugin, extension, toolbar or search bar that is installed in your browser. After removing such things you wont be getting any popups when you browse the internet. I always recommend you to install only trusted programs and do custom installation to view if any unwanted software is being installed. Please feel free to contact us should you need any further assistance.

All kinds of pop ups some of them even relate to the site I am on, there are video pop ups also. pop ups that start off "DOWNLOAD NOW" or "YOU MAY HAVE BEEN INFECTED" . The most annoying is there are so many it covers the screen. they even show up on reference sites I tried your 30 trial for AVG PRO but it did not help at all
