Reports started coming in yesterday of multiple infections from the "Here You Have" worm (a variant of W32/VBMania@MM). Here are several articles detailing the worm.
If you are using the practices I advocate (e.g. not clicking on any link sent via email that you weren't expecting to receive, and not giving your user account administrative privileges) then your risk of getting this virus is low. If you have the ability to filter out websites on your network, I would filter out the expressions "sharedocuments.com" and "sharemovies.com" as these are the sites that hosted the original files.
As always I highly recommend that you keep your anti-virus up to date and that you patch your system early and often.
