Re: Is this a worm or a virus? If not, what?

Windows Update experts, here's one for you.

Rock's explanation (below) fits my symptoms - I do indeed have auto updates
scheduled for 3am daily. Following some other advice I got, I looked at
http://support.microsoft.com/kb/927978. That page recommended three steps:

1. "Remove security update 927978 by using the Add or Remove Programs item."
I couldn't do that because 927978 did not show up in my list of updates.
2. "Delete the MSXML4.dll file from the %SystemRoot%\System32 folder." I
did that, and so far (one day later) no new log files have appeared.
3. "Repair the previous installation of MSXML 4.0 by using the Add or Remove
Programs item in Control Panel." I don't know how to do that.

My concern is the perhaps my system needs a functioning installation of
MSXML, and I assume that present I don't have one.

~ TIA
