description: I point out Yahoo's crude email virus filter, which replaced the string 'eval' with 'review' to block malicious scripts. This created unintended search results for 'medireview' instead of 'medieval' across historical and travel sites.

Yahoo's been filtering e-mail viruses. Good, but they've been [a little crude](http://news.bbc.co.uk/hi/english/sci/tech/newsid_2138000/2138014.stm). So a Google search for [medireview](http://www.google.com/search?q=medireview) reveals a book on [Middle Ages: that **medireview** chronology](http://www.st-francis-lutheran.org/nyt_11Mar01.html), and a [treasure ride](http://www.tuscany-adventures.com/Medieval.htm) with medireview jewels, a medireview city and medireview treasures.
