Dude you shouldn't be sending people to hacker sites like that, I only went there because I have tons of protection but that thing comes up with skull and crossbones right across the top, looks like a good place to pick up a real nasty.
Hackaday is not a "hacker site". As a frequent visitor to quite a few "hacker sites" I've never had a problem. You've got more of a chance getting something nasty on your PC just going to a MySpace page or letting an email open in your Outlook preview pane then you do going to a "hacker site." So-called "hackers" tend to police themselves pretty well and if an actual "hacker site" was doing something nasty, other "hackers" would notice and do something about it.
The most frightening hackers don't use "leet" speak, they don't use skulls & crossbones, etc. If they want to own your box, they'll do it in ways that you'll never suspect and likely never see. In fact, your box may already be owned right now and you would never know it.
