HTTP Possible Malicious PDF File Detected

Anyone else see a very high false positive rate for this attack?  I'm curious if anyone can provide insight into this particular alert and perhaps what characteristics and signatures are used to detect.  Just curious for any thoughts, suggestions, or feedback.

I've even seen this alert occur when downloading PDFs from McAfee.com including the NSP admin guides.

Re: HTTP Possible Malicious PDF File Detected

There is an article on talking about techniques used in detecting malicious PDF file, hope it will help a little. Hope someone can develop a PDF reader which carries the function to tell whether target PDF is safe.
