A new worm called Win32.Invalid.A@mm has been detected. This worm e-mails itself to masses of inboxes at a time, disguised as a warning from Microsoft.

Central Command, a U.S anti-virus vender has rated this worm as a medium risk. However it has been reported that the worm may pose as a greater threat as it is still in its early days of its cycle.

The worm is emailed under the disguise of support@microsoft.com and reads “The SSl Protocol is used by many companies that require credit card or personal information, so there is a high possibility that you have this certificate installed. To avoid being attacked by hackers, please download and install the attached patch. It is strongly recommended to install it because almost all users have this certificate installed without their knowledge.”

The worm can infect machines running Windows, Windows NT and Windows 2000.
