Facebook is deprecating the Graph API Explorer App as of today, and the Profile Expressions Kit will deprecate on October 1. The latter is due to low adoption, Facebook said.

Watch out for these links and anything posted from the Graph API Explorer. The malware cannot affect computers running Apple OS X or Linux, so Windows users need to be especially vigilant.

But there are some hints in Facebook’s Graph API code that could indicate otherwise. Lines of code referring to “rssfeeds” have recently started to appear in Facebook’s Graph API code.
