does anyone know of any websites that talk about some wikipedia link giving someones computer a virus?

Thinking about this simply, Wikipedia is a fully editable source. Meaning, it is possible for a user to put a link in there to another site that may or may not be malicious. This isn't Wikipedia's fault, and would be caught after 1-4 days.

Although, I have never had it happen to me, because I barely use Wikipedia as is. That doesn't mean it hasn't happened or isn't going to happen.

Christopher is basically correct, in that the "sacred" open and instant editing regime on Wikipedia makes it all too possible, perhaps even likely, that someone has included a link containing malware on Wikipedia at one time or another. However, I too am unaware of any specific incident where this has actually happened. In a weird way, Wikipedia's all too open editing policy might serve as a form of protection, in that hackers may consider Wikipedia to be a way too easy target, and therefore beneath their contempt and not worth the effort. That could go a long way toward explaining why such a easy target isn't full up with viruses.

However, it is incorrect to assume that a malicious link would necessarily be removed within "1-4 days". It is an urban legend that Wikipedia has a fact-checking crew that eventually checks every edit to articles. In fact, Wikipedia has never had any peer review process; whatever corrections are made are done by people randomly showing up and happening to catch it. Indeed, the 800 or so active admins are a grossly inadequate volunteer workforce to check on every edit, particularly when edits are coming in every few milliseconds.
