Worst computer episode in a movie?

Cuban Devil writes: Yesterday I rented a blu-ray movie and put myself to watch The Social Network. No comments about the story, but Zuckerberg's narrated performance on hacking Harvard servers made me wonder which was the worst computer action performance I had ever seen on a screen. I leave here my vote: worst episode was when I had to see Mr. Goldblum upload a virus, using a Mac, in a time it did not connect even to an ethernet network, and compromising the entire Alien fleet. Is anybody capable of remembering something below that?
