It doesn't always point to StackOverflow. I saw at least one article from geekipedia.
Oh, and I did visit the site. After all, xrc seems to have suffered no ill-effects after a visit sans-ad blocker and I'm running a fully-patched system with up-to-date anti-virus software. Unfortunately, that site may have put a virus on my system (of the silently turn on your webcam variety). And I'm sorry, Jeff, but I am talking about your old laptop here.
I only noticed because there was suddenly an oem02mon process that was pegging the cpu every few seconds, making the computer not show my keystrokes as it should. It seems to have let me kill it without complaint, I haven't had this system long enough to know if that process is maybe supposed to be there, and google gives it mixed reviews (malware does sometimes use that name, but it's also normally part of some Dell laptop webcam drivers). So I might just be over-reacting, but I wanted this out there right away before anyone else visited the site.
I'll post back later (meaning tomorrow at least) if I keep seeing suspicious behavior, and I will have my eyes open (and maybe boot from a flash drive to scan the disk, just in case).
Unfortunately, since they do link back to the original content credit is given as per the license and I don't think StackOverflow has any real legal recourse. The only good news I have is that if they really did give me a virus, Google is pretty good as spotting that kind of thing and it will kill their search ranking, meaning the site won't make money and it will just go away on it's own.
Update: After some looking, I don't think the laptop caught a virus, but I do think one of the ads tried to give it one.
