kiki , hello and welcome  :thumbsup:

First , download HiJack This :
http://www.thespykiller.co.uk/files/HJTsetup.exe

This will download HiJack This to your computer, choose "Save" and navigate to the folder where it´s saved and doubleclick upon it.
This is a complete installer that installs Hijackthis onto the computer to C:\Program Files\HijackThis and makes an entry in the start menu & allows you to have a shortcut on desktop as well.

then.......
Doubleclick the HJT icon on your desktop, hit "Do a system scan and save logfile". Save the logfile and a txt-file will be produced.. Copy that one and paste it here and we´ll have a look at it.

Since you have no internet, use a connected computer to download the file and put it on a floppy or CD .

Also , at the same time, get this tool that will mend your internet, "LSPFix":
http://www.greyknight17.com/spy/KillBox.exe
Install it on your broken system, but do nothing with it yet,not until you have posted a HiJack This log.

regards

Die Hard :)

 kiki :)

There seems to have been an error with the download link, you where supposed to have downloaded "LSPFix". But in fact ,this turned out to be very good, when we will need Killbox.  :P

Now let´s try this:

Click on (windowskey+R) and type Services.msc>OK and in the window that opens,scroll down until you find Windows Stability Route (WSR)
Doubleclick upon it and in the new window click the scrollbar at "Startup type" and set it to "Disabled". Click the Stop button , Apply and close.

Then run HiJack This and put a checkmark next to :
O23 - Service: Windows Stability Route (WSR) - Unknown owner - C:\WINNT\construct.exe (file missing)
Press "Fix checked" and answer "Yes" to the prompt.

Now open Killbox, by Option ^ Explicit, and checkmark "Delete on reboot".
In the field "Full path of file to delete" paste this first:
C:\WINNT\construct.exe
then click "no" when prompted if you want to reboot.
Then paste this filepath:
C:\Windows\System32\remon.sys
Now,let the system reboot. If it doesn´t by itself, do it manually.

After reboot, go immediately to Trend Micro´s online scanner and let it remove whatever it finds:
TrendMicro (http://housecall.trendmicro.com/)

Please,save the log and post it here together with a new HiJack This log.

regards

Die Hard :)

Please go here and download   Ewido Security Suit:
http://download.ewido.net/ewido-signatures-full-20051116.exe
It´s a complete installer, supplied with the latest definitions designed to be used in situations like this.
You need to burn it to a CD, when it´s 4,3Mb in length.

At the same time, download and add to the CD also the "WinsockFix" : http://www.tacktech.com/pub/winsockfix/WinsockFix.zip

A quick guide to Ewido Security Suit is found here:
http://www.greyknight17.com/spy/Tutorials/ewidoQuickGuide.pdf

1. Install ewido security suite
2. Reboot your computer to Safe Mode. You do this by rebooting and during the startup process tap the F8-key repetedly until a screen appears where you navigate with the arrow keys. Choose "Safe Mode" and hit "Enter".

Once in safe mode, go on with this:
3. Launch ewido, there should be an icon on your desktop double-click it.
4. The program will now go to the main screen
5. Click on scanner
6. Click on Complete System Scan and the scan will begin.

7. On the first alert, a window will open prompting you to take action. Checkmark "Remove" and "Perform action on all detections".
Screenshot:  http://i18.photobucket.com/albums/b123/DieHard53/EWIDO2.jpg

8. Once the scan has completed, there will be a button located on the bottom of the screen named Save report
9. Click Save report.
10.Save the report .txt file to your desktop.
11.Now close Ewido security suite and reboot normally.
12.Run the "WinsockFix" and follow the prompts on the screen.
13.Try your internet connection.
14.Copy the Ewido report (to the CD) and post it here for review.

regards

That seems to have taken care of one infection  :thumbsup:

Now we have to deal with the evil rootkit.

Please go here and download F-Secure´s Blacklight
http://www.f-secure.com/blacklight/try.shtml

All information needed is supplied on the homepage:
http://www.f-secure.com/blacklight/help/

If possible, run the tool in safe mode.
Before you start the cleaning, disable the restore points just to make sure no baddies are hidden there , displaying their nasty noses once  we´re through

  Disable restore point (http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001111912274039?OpenDocument&src=sec_doc_nam)
Create a restore point (http://www.microsoft.com/windowsxp/using/helpandsupport/learnmore/systemrestore.mspx)

If you need any help along the way, please come back and ask. :D

Post by: Paddy on November 17, 2005, 02:20:14 PM
Hello,kiki  see if this helps ..

1. Close all open programs.
2. Right-click My Computer on the Windows desktop, and then click Properties.
3. Click the Performance tab.
4. Click File System.
5. Click the Troubleshooting tab.
6. Check Disable System Restore, click OK, and then click Close.
7. Click Yes to restart. This disables the System Restore feature and will purge the contents of the _RESTORE folder when the system is restarted.
8. After cleaning the infected files, repeat steps 1 through 7, except in step 6, uncheck Disable System Restore.

Sorry, my bad. I didn´t look at the top of your log closely enough to see that it is a Win2K system.
Win2K doesn´t have the system restore.

Please go on with the "Blacklight" tool
