HTTP encoding for ms10_xxx_ie_css_clip

[David Porcello <DPorcello () vermontmutual com>]

Hi all - I'm having an issue with client AV (McAfee) detecting ms10_xxx_ie_css_clip as "JS/Exploit-BO.gen". I've tried 
enabling SSL and all Metasploit evasion options:

HTML::base64 Enable HTML obfuscation via an embeded base64 html object (accepted: none, plain, single_pad, double_pad, 
random_space_injection)
HTML::javascript::escape Enable HTML obfuscation via HTML escaping (number of iterations)
HTML::unicode Enable HTTP obfuscation via unicode (accepted: none, utf-16le, utf-16be, utf-16be-marker, utf-32le, 
utf-32be)
HTTP::chunked Enable chunking of HTTP responses via "Transfer-Encoding: chunked"
HTTP::compression Enable compression of HTTP responses via content encoding (accepted: none, gzip, deflate)
HTTP::header_folding Enable folding of HTTP headers
HTTP::junk_headers Enable insertion of random junk HTTP headers
TCP::max_send_size Maximum tcp segment size. (0 = disable)
TCP::send_delay Delays inserted before every send. (0 = disable)

Has anyone found a combination of encoders that has worked well for AV bypass? Is there a way to obfuscate this module 
with a 3rd-party obfuscator (such as Dean Edward's packer or javascriptobfuscator.com) and then re-import for use in 
Metasploit?

Dave.
