This was a McAfee Site Advisory commercial of what happens when you visit goggle.com. We see notes writing that you shouldn't try it at home. Then a finger presses a laptop (possibly a Dell)'s on/off button. Then the user types in the website. Weird pop-ups happen while very, VERY dramatic music and a creepy choir play. At the end, a customized Blue Screen of Death appears. Then more notes as no animals were harmed in the making of this commercial. Then the commercial ends.
Scare Factor Edit
Medium to Nightmare, the weird pop-ups, the music, and the choir will scare a lot of people. Do not watch this commercial at night.
