The Storm malware, which first appeared in January of this year, is showing no signs of slowing down -- just this week reinventing itself as a Web site membership confirmation message.  Click here for details.

* Do not follow unsolicited links.
* Install anti-virus software, and keep its virus signature files up-to-date.
