Microsoft has determined that one of the technologies used in the recent criminal attacks against Google and other corporate networks was Internet Explorer 6. Customers using Internet Explorer 8 are not affected by currently known attacks.
We recommend that anyone not already using Internet Explorer 8 upgrade immediately. Internet Explorer 8 offers many additional security protections. Upgrade to Internet Explorer 8
If your computer has Windows XP, we recommend that you upgrade to Service Pack 3 to gain the maximum protection available. Be sure you also upgrade to Internet Explorer 8.
Microsoft teams are continuing to work on a comprehensive security update that will address this vulnerability. We will take appropriate action to protect customers when the update has met the quality bar for broad distribution.
