A New Worm was discovered today called "W32. Novarg".
It shows up in your e-mail box with a"spoofed" e-mail from your Ip, mine was spoofed with a name of a friend on the same Ip. So it looked legit. And it showed as a txt file, safe right. NOT
It contains a file called "Text.txt" or similar.
If you don't have todays (1/26/04) latest virus definitions it won't show up as a virus, then when you open it , it writes to the REG and installs some .dll files to your system.
It is a DOD and mass e-mail worm.
It's a real pain to remove, reg edits and rescans. Even then some of the files can't be removed, just quarantined.
So be careful and download the latest definitions from your virus provider.
Symantec has removal info if you need to remove it.
