Not answering your question but why do you allow pop-ups & ads ?You can use an Ad Blocker that will stop them unless you want the ads etc !!
For clarification, is that to be used at the time the popup is present? I couldn't see how it'd work subsequently, nor actually did see anything of concern.
Is 127.0.0.1 still valid?
Thanks! Somewhere, where the creepy crawlers of my mind live, I had the idea that 0.0.0.0 was a replacement.BTW has my query about where to park Process Explorer been overlooked?
