Subject: Help, possible rootkit

Any odd traffic coming to or from this machine?  What's a sniffer telling 
you.

I might've missed it, but is this a home user machine or in a business 
place?

Do you have issues running in safe mode?  If you don't, then it would sound 
like the rootkit's not running, which means you can probably look at some of 
the normal places for a file/processes loading/starting.

I don't know about the rest of the list, but I haven't seen or heard of too 
many process hiding xp rootkits that are undetectable by some of the basic 
methods mentioned.  See www.rootkit.com.  At least, not floating around on a 
single PC that sounds like an unlikely "high value" target.  It seems much 
more likely that XP or an application is just crapping out on you, and if 
you can't figure it out,  reinstall.  If nothing is revealed after trying 
some of the methods already suggested here and by others, I think the 
likelihood -- given the info you've told us so far -- makes it's unlikely 
that it's a rootkit.

My 2 cents.
