Microsoft released a patch today rated “Critical” for users of IE 6,7, and 8. This is a follow up to the IE bug reported a few days ago, that has been in circulation for months, and (hopefully) finally closed today.

Microsoft’s security bulletin lists the affected software and reasons behind the patch, and below the post includes links to dozens of patches (per OS, version of IE, etc.).

Be sure you’re installing the correct version for your version of IE and your OS. The easiest way to do this is to use Windows’ Automatic update service, but if you need to you can also check them manually.

To see the version of Windows you’re running, you can follow the advise of Dave Taylor here.
To see the version of IE you’re running, follow the quick steps in this MSDN blog post.

IE has always been one of the browsers with the most security flaws in it. Try Firefox or Chrome (although neither are 100% secure), and be sure to always practice Safe Surfing with your XVU Drive.
