Usually there isn't a lot of discussion due to our track record of updating the moment we can, especially in response to vulnerabilities that may effect our products. Our IPS System should updated with the proper patterns (if not yet, it will be imminently) from with a VRT rule to catch it via this method, and for pure AV scanning (not the best way to get it, but still)...
The avira engine will detect some infected files as: HTML/Shellcode.Gen HTML/RCE.Gen HTML/Silly.Gen
And they may choose/develop patterns for even more variants as it develops. FYI the patterns were active before microsoft released the public information.
