Pat et al, the way to stop the popups short of a power cycle is to go into "Network and dial up connections", right click on your lan connection, select properties, and check the box ot the bottom of the "general" tab labeled "Show Icon in Task Bar when Connected". Then OK out.
This will add an icon that looks like two terminals to your task bar. When you get hit with this popup flood, right click the icon and select "Disable". Cuts off the source of the popups. Shut down all browser instances. Now you can re-enable which can be done from the "Network and dial up connections". To make this even easier, right click on your lan connection, select "create shortcut" and click yes to put it on the desktop. Move it to whereever you want and double click to enable.
