QUOTE
We’ve also been made aware of some third party solutions being made available for this vulnerability.
Some of these solutions make modifications to Windows itself to bypass the attack vector of the vulnerability. Of course, while the IE team is working on an update to address the problem, we certainly recommend a defense in depth strategy that involves third party tools such as AntiVirus or IDS/IPS solutions. However we cannot recommend third party solutions that modify the way the product itself operates.
