Hmm
Ok, popups are caused by cookies stored on your hard drive. They are needed but not essential. There are several solution possibilities: First, download a firewall from
www.download.com Look for one with a free license and the highest rating/voters. Then clean out your Internet Temporary files, go to Tools --> Internet Options on your browser and delete/clean/clear anything you can in the General Tab. In the next tab check your security level. Set it to medium in case it has been modified. The next tab should read Privacy. Click on Advanced button and check "override automatic cookie handling" Set them to promt for both or at least the Third Party cookies. This will prevent any new ones from getting on. You can also Edit a particular website's cookie options. Then run ad-aware and any antivirus you have. After that, install the firewall. This should prevent the spoiled cookies from triggering outside sites.
Now try restarting and see if anything shows up. Don't reboot before doing all the clean-ups and the firewall.
You will be asked to allow the cookies for each site every time you visit a web-site, but you can test it this way to see if you get popups still. After a little while try to accept all first-party cookies and mayyyybe the third party ones as well if it gets annoying to click the cookie permission every time. This way you know what websites are trying to put cookies on your pc and can deny suspicious ones ...
Lastly, i wouldn't suggest watching that video again

Good luck!
