Download and unzip latest version of "
Process Explorer from SysInternals (now owned by Microsoft). Run the executable. There's a row of icons, just below the top row of pull down menus. Select (left-click) the "gunsight " icon from the end of icon row, drag it onto the annoying pop window, and release the mouse selection button. The process controlling the popup should be highlighted in Process Explorer window.
What is the
name of the process controlling the popup?
When you right-click the offending process within Process Explorer, you have a context menu which gives you option to "suspend" or "kill" the offending process.
If it's your internet browser, you don't want to suspend or kill it. We'd need to use SysInternals Autoruns or something equivalent to identify the responsible "helper" program within the browser first; and then just remove or disable it from starting with the browser.
If it's not the browser, you can probably just "suspend" the offending process temporarily and see if that stops the repetitive popups. Then later, need to determine if and how to get rid of it.
Your best course of action would be to "wipe" the hard drive and start over with a clean installation of the operating system. Otherwise you should scan for and remove all the "bad boys" from your system. See the "Computer Hope Forums -> Software ->
Computer Viruses and spyware" subcategory for this. Start with
