pe386-msguard-lzx32 & some spywares

Posted on 2006-10-26
Last Modified: 2012-06-21
im down to the last 3 items which is really hard to delete even in hijack this or commandprompt.

1. rootkit? pe386-msguard-lzx32 - i have no idea how to remove this. i think this one is opening & listening the port and send sentivite information to the hacker's computer.

2. dll's which are loaded even on startup safemode command prompt only.

i could not delete these dlls because these are loaded already even on command prompt only?
this is the deskbar spyware i think. cause i could still see it on the windows explorer's toolbar.
i have deleted all deskbar.dll related files except for the last 2.
xxyxtt.dll & pmkh.dll

is there another way to prevent them from loading? which files to check?
or is there a way to disable an already running dll?

im using WINXP pro btw.

last resort is to reinstall the windows.
suggestions are appreciated.

use a program called killbox located here

give the path to the dll files and check delete on reboot option this will get rid of it.

What kind of file is the pe thing and where is it located? you can romove the file using the same method if you wanted.

there appers to be really a few things you want to do to get rid of this rootkit.  

here is a great post where they deleted it I figured there was a service and a few things to it but I didn't know 100 percent here you go.

this nasty rootkit - pe386 hides itself.
i just learned about this on wiki

i do not know how to delete it. it's not even detected on hijackthis.
It was detected by a smitfraudfix.cmd
while im trying to fix the spywares - smitfraud and astakiller

it says i need to download a rootkit software.

but i dont trust any of the sites that i found.

thanx for the killbox.

rootkit revealer will help but it will only give you the text file it is writing to. Use avenger found here:\ and do you have the log from smithfraudfix?  If I could get some locations I could help you out more.

>  If I could get some locations I could help you out more.

it says evrything is clean
at the end of the raport.txt

it just says
rootkit detected use rootkit tools to fix it.

no other locations.

i just found out it starts to delete all the exe file that i run
in "start/run" after reboot.

First install this free utility
it will help you to identify the files that loaded when boot
try it in "safe mode command prompt only" – this is very important so the spayware will not be working there-
you may put it in the root of the D:\  
then you can use the command prompt to run it (use the autoruns.exe)
then seek all the taps there to seek your files and disabling it.

And also you can use this free utility to reveal the RootKit

and the other one from AVG

and finally this is more details about "Anti-Rootkit Software - Detection, Removal & Protection"

Smitfraudfix does detect drivers from those 3 rootkits mentioned, but it also has false positives, I had a couple of false positives reported with the smitfraudfix scan.

What you should do is to check for rootkits and  run Gmer:
Download GMER from here:

Unzip it and start GMER.exe
Click the rootkit-tab and click scan.

Once done, click the Copy button.
This will copy the results to clipboard.
Paste the results in your next reply.

If you're having problems with running GMER.exe, try it in safe mode.

If Gmer doesn't find any rootkit then that is halfway clear.
Next is to unload the driver pe386 using avenger or just stopping the service, if there are no drivers to unload then it is false positive.

deskbar.dll<-- is a variant of Alcan worm/P2PNetwork worm

xxyxtt.dll <-- looks like haxdoor

pmkh.dll<-- looks like qoologic file, could also be vundo

Can we look at your hijackthis log please? hijackthis log can tell us what infections those files belong to by looking at what lines in hijackthis they are running from.

Please download HijackThis 1.99.1
Open Hijackthis, click "Do a system scan and save a logfile" don't fix anything yet.

Then upload the logs to any hosting sites,
or go to the below link and login using your Experts-Exchange username and password.
Click on "Expert Area" tab
type or paste the link to your Question
"Browse" your pc to the location of your Hijackthis log and click "Upload"
Copy the resulting "url" and post it back here.

OR: paste the log to either of these sites:
then at the bottom left corner click "paste"
Copy the address/url and post it here.

2. or at -->
and click "Analyse", click "Save".  Then post the link to the saved list here.

Sorry to hear you had to reformat, maybe it's for the best, at least now you have a squeaky-clean system.
