How can I find out if a website is injecting adware when the "checking your browser-wait 5 seconds" interstitial page is shown? Exactly what goes on in the background during this "test"? I know a cookie is placed on my PC because if I clear my history after gaining access to the site, the 5 second page pops up again if I click on anything else on the page.
Is there a way to decode the cookie into plain English?
