Is anyone else having issues with Muggletnet.com?

I just tried to go there and the same thing popped up. Apparently, the site is linked to doubleclick.net which is listed as a pop-up/spam site. I have been on the site many times before, but maybe things have changed recently. If it truly does install malicious things onto your pc, I wouldn't go there anymore. You are able to ignore the warning if you want, but I would look for another Harry Potter site, there are many.
