The previous message has a bad link I am trying it again. The full Written link is,

http://www.symantec.com/avcenter/venc/data/w32.sircam.worm@mm.html

I have added it also at the bottom of this message below the picture. It appears as the URL is too long to fully link properly. As I said if you want more information or if you have friends or clients that send you email in Spanish there are some translations of the common messages at the Symantec (NORTON) link below.
