Long ago, I lost access to the popular geek paraphernalia website, ThinkGeek.com. Finally took the time to track it down to NOD32's active filter. If I take my browser off the active filter list or add *.thinkgeek.com to the except list, I can access ThinkGeek.com. Problem solved. However, I'm curious why this site is blocked. Firstly, I can't find anything that says why active filter blocked the site. No messages. No logs. And I've looked at the page's source code, and I don't see any particularly questionable code (though granted, I don't know what the active filter is looking for). Secondly, what exactly is questionable about it so that web designers can avoid getting similarly blocked?
