    none of the anti malware programs is able to remove the stamplive adware from my computer. I’m afraid the only solution will be to go back to factory settings.

    I had price minus ads popping up often in all webpages.It was driving me nuts.! I removed an extension from my browser (Firefox). I started deleting the extensions that I knew were not vital. And no more popups! I do have a couple of malware programs, and they too failed to remove these ads. But removing the extensions from Firefox + the add-ons section its what did the trick! I also did the same thing to google chrome browser, I deleted some add-ons, and extensions as well.
