I don't know about Symantec, but for McAfee, dat version 4282 (current before today) didn't detect it at all, 4283 could detect it but not clean, and 4284, out within the past two hours, can detect, block, and clean.

dialup users), and I'm trying to figure out if this is something new,
or
just something old that we finally are getting. I'm not entirely sure it's a worm, it almost appears to be an
auto-rooter
with quick spreading ability (fine line between that and a worm, I suppose). Has anybody else seen something with these characteristics: Host scans local subnet first, looking for vulnerable machines and

up port 4444 on the remote host, and running the following:
