Post #1
Could somebody please help to remove a trojan horse virus? I have recently acquired the Trojan Horse virus "Krepper.S". This virus is still on my system despite numerous attempts to delete it! I have downloaded spybot, adaware, trojan hunter, avg & anti-trojan shield. However, even though these programs do find the problem files and I delete them, but the trojan returns to my pc within the same session every time. I've also tried to delete the problem file in the registry files - but it still comes back. I am NOT pc literate, and would like instructions in simpleton, plain English terms please. Thank you! :oops:

Greetings and welcome to TomCoyote.org!

Important: Create a folder on the C: drive called C:\HJT.
You can do this by going to My Computer (Windows key+e) then double click on C: then right click and select New then Folder and name it HJT.
Download HijackThis into this folder.

If required a tutorial is here = Hijackthis Folder Tutorial

Links to Hijack This! v 1.98.2:

http://tools.radiosplace.com/HijackThis.exe
http://spywarewarrior.com/files/HijackThis.exe

Run it from that folder.

Click "Scan".

DO NOT "FIX" ANYTHING WITH IT YET!!!
FIXING THE WRONG THING COULD RENDER YOUR SYSTEM INOPERABLE!!!

Click "Save log".

Reply to this thread, and "copy/paste" the ENTIRE CONTENTS of the log file into this thread.

For your information…. I couldn't find the 2 windows files (exe & dll) while in safe mode, and I had made sure that they weren't hidden, so not sure what is going on?
Post #7
It's OK that you couldn't find those files. They're gone now.

The log looks good. :thumbup:

GOD bless!!!

Items you may wish to consider to harden your defenses against future infections:

Read "How did I get infected in the first place?" here:

http://boards.cexx.org/viewtopic.php?t=957

Download IE-Spyad here:

https://netfiles.uiuc.edu/ehowes/www/resource.htm

IE-Spyad puts over 4000 known malicious web sites into IE's "restricted zone" to help prevent you from getting infected.

Check your browser settings here:

http://browsercheck.qualys.com/index.php

A series of "tests" (and suggested fixes) to help tweak IE's settings to help prevent infections when surfing the web.

Follow safe Internet practices:

1. Keep your virus definitions up to date, and scan your system regularly.

2. Don't open email, or download attachments from unrecognized email addresses.

3. Be careful when downloading email attachments, EVEN FROM PEOPLE YOU KNOW! Many virii, worms, and trojans infect a persons system then immeadiately spread themselves to the people in the infected persons addressbook via email attachments.

4. Be careful downloading files from the Internet. Scan all downloaded files with a reliable UP-TO-DATE antivirus program. Scan "zip" files BEFORE unzipping, and scan all unzipped files BEFORE USING THEM.

5. Keep your Windows and IE current with all the latest patches and updates.
(Personally, I'm NOT recommending S2 for XP at this time)

:D Thank you for all your help. I have run my Anti-virus software and it can't locate this trojan any more - great! However, whenever I try to log into hotmail I still get the following message "Spyware S & D" reports that you want to download "doubleclick". This is a known threat. Do you want to block this dowlnad?", and gives a "yes" or "no" option. Of course, I choose "yes" to block it! Is this related at all to the trojan horse virus, or is it something different again? Could you please help to remove this too? Thanks!

Hello Micah_6:8! Although the trojan has been removed, I still have one more problem. Are you able to help to remove this too? Whenever I try to log into hotmail I still get the following message "Spyware S & D" reports that you want to download "doubleclick" or "avenue etc". This is a known threat. Do you want to block this dowlnad?", and gives a "yes" or "no" option. Of course, I choose "yes" to block it! Is this related at all to the trojan horse virus, or is it something different again? Thank you.
