A new email virus (technically a trojan) is currently making the rounds.  This one is an attachment to a message with the following text:

The attached file is a zip file, named nz.zip, and is small, at only 9.8 kilobytes for one variant.

At least some variants of this virus are, as of this writing, not detected by Norton, Trend Micro, or McAfee.  (Click the thumbnail to see the full size results in a new window.)

The trojan downloads several other malicious programs onto your computer, and also disables the Windows firewall, and the Windows Security Center, rendering your computer vulnerable to other intrusions.

It also uses techniques to insert itself into Internet Explorer, Firefox, and Opera browsers, thereby poisoning them with malicious code, probably intercepting passwords to websites and other activities.
