As you are probably aware this is pretty much a brand new listing as it is dated 09/14/2011, and has no technical information. I only found one non-MS listing on Google which was a German site. Google translated it to reflect its inquiry was also new with no response as of yet.

I was wondering of the possibility of a false positive with a new definition release. Definitely something to watch.

Hi big al 41,

Do you recall the file path? I wouldn't worry too much since MSE did what it was meant to do.

To be sure you could do an online scan with ESET from the link below.

this is the path that this Trojan took:

containerfile:C:\Users\Al\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\5\62dd8a85-2e2ae496
file:C:\Users\Al\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\5\62dd8a85-2e2ae496->buildService/MailAgent.class

Hi big al 41,

When your browser runs an applet, the Java Runtime Environment (JRE) stores the downloaded files into its cache folder (C:\Documents and Settings\username\Application Data\Sun\Java\Deployment\cache) for quick execution later and better performance. Both good and malicious applets are stored in the Java cache directory and your anti-virus may detect them and provide alerts as what you experienced with MSE.

Notification of these files as a threat does not always mean that a machine has been infected; it indicates that a program included the viral class file but this does not mean that it used the malicious functionality. However, when alerted to this type of threat, it's a good practice to clear the Java cache and clean out Windows temporary files.

To do that I personally use TFC.

Download then double-click TFC.exe to run it.

TFC will close all programs when run, so make sure you have saved all your work before you begin.

• Click the Start button to begin the cleaning process.
• Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two.
• Please let TFC run uninterrupted until it is finished.

Don't be alarmed when the desktop disappears, it will reappear upon reboot.

Once TFC is finished it should restart your computer. If it does not, please manually restart the computer yourself to ensure a complete cleaning.

Also ensure that your Java is up to date at all times. The most recent update is Java 6 Update 27 though Java 7 is now available as well. I have installed the Java 7 version and have had no issues so far. The choice is yours as to which you would like.

Also make sure that all older versions of Java have been removed from your system by going to Add/Remove in XP or Programs and Features in Vista/Win7.

If you'd feel more comfortable try the Online scan I mentioned above.

Not sure why my link for TFC did take.

Here it is--> TFC

Sorry about that.

Here's a link to Java updates if you'd like it. Choose the JRE Download.

thank you it worked well
