Microsoft Security Essentials 2.1

If you are running a previous version of Microsoft Security Essentials, such as version 1.0.1407.0, 1.0.1500.0, 1.0.1610.0, 1.0.1961.0, or an earlier version, you may notice an action item that prompts you to upgrade to the latest version of the program. You are prompted to do this through the Microsoft Security Essentials user interface, through a pop-up window, or through a "toast" message. Additionally, you may notice an "Important" or "High priority" download, Microsoft Security Essentials Client update package - KB2254596, on Microsoft Update (http://www.update.microsoft.com) that offers an upgrade to the latest version of Microsoft Security Essentials.

Important If you are running a beta version of Microsoft Security Essentials, we encourage you to upgrade to the latest version. By upgrading now, you help make sure that you have continuous protection against viruses, against spyware, and against other malicious software.

There're rootkits floating about now which AV can't defeat. Lucky, the virus is so sophisticated it has its own built-in AV. True story.

If you're bored, find somewhere else to play other than these forums.

That was on topic bill. I'm pretty sure people interested in keeping their AV up to date would also be interested in the TDSS rootkit.

Don't play the clever guy, it doesn't suit you.

Good heads up Nick - Many thanks.
