If there is anything more obnoxious than the FaceBook "Like my blog!" popup window , it's a FaceBook "Like my blog!" window, preceded by a generic popup window. It's possible that a blog which starts with two popup windows, one followed by a second, represents a blog owner who honestly wants people to enjoy her (his) blog. Even so, a blog that starts out this way is going to present a security analysis challenge, at best. Seeing the growing popularity of the FaceBook popup (among blog owners, anyway), it's possible that the security scanning processes will, eventually, find a way to bypass the FaceBook code, and continue scanning. This may avoid some spurious malware classifications - if FaceBook developers can find a way to certify a genuine FaceBook popup.
