Another Mass Mailing Worm, W32.Novarg.A@mm, is circulation around the Internet. I've received a couple already today. They contain an attachment that will end in pif, .scr, .exe , .cmd , .bat or .zip. More information can be found at the Symantec Web site (among other places) at: http://securityresponse.symantec.com/avcenter/venc/data/w32.novarg.a@mm.html
