Re: 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.

I have ran Process Explorer, Code Stuff Starter but nothing shows up in the
list as using this 25-30% of my CYP.  I also updated and ran PestPatrol,
NortonAV, etc but nothing is detected which is why I think I have a rootkit that has patched the kernel and therefore not allowing any of these programs
to detect it.

Anything else ?

First check to see what processes are running. TaskList is built in but I
would recommend.
http://www.sysinternals.com/ntw2k/freeware/procexp.shtml

Get to know your machine and what processes are running normally.  With
25-30% CPU it should stick out like a sore thumb.

Oh yeah don't run as admin (see )http://blogs.msdn.com/aaron_margosis.

I have noticed that my XP system is behaving like I have a rootkit.

- My mouse is jumpy (it freezes for a second when I move it around the
desktop) and the minimized Taskmanager in the systray shows I have around 25 - 30 % usage, but when I open it, there is no process listed using this
much.
- I did a netstat, fport, openports and none of these show that I have any
odd ports open or any connections established.
- even when I disconnect from the Internet these symptoms do not stop.
They
stop if I reboot, but then start again.

I have ran VICE, Klister, PatchFinder and RkDetect from rootkit.com and
they
could not find anything.

Any more suggestions ?
Any more rootkit finding tools for Windows ?

Thanks
Bill
