Win32 Trojan Dropper Problem!

January 27, 2007 at 06:56:07
Specs: Windows Xp SP1, AMD Athlon XP 1800+ 256Mb

Hello, I have recently been infected by a Win32.Trojan.Dropper.. I know this because it appear in a small window saying "Explorer.exe is probably infected with Win32.trojan.dropper". I've tried to use Ad-Aware to get rid of it and Stinger. Isnt there a program or a tool that I can get rid of this trojan. The window that displays this message seems to come from the actual trojan itself which keeps displaying it everytime it makes my PC to restart and start windows again. I have disabled System Restore.
Any help please?

Thanks a lot
From Steven

Please post a Hijack This log so that the files associated with the virus/spyware/hijacker can be identified.

Please download HJTsetup.exe from this link http://www.thespykiller.co.uk/files/HJTsetup.exe to your desktop.
Doubleclick on the HJTsetup.exe icon on your desktop.
By default it will install to C:\Program Files\Hijack This.
Continue to click "next" in the setup dialogue boxes until you get to the "Select Addition Tasks" dialogue.
Put a check by "Create a desktop icon" then click "Next" again.
Continue to follow the rest of the prompts from there.
At the final dialogue box click "Finish" and it will launch Hijack This.
Click on the "Do a system scan and save a logfile" button. It will scan and the log should open in notepad.
Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log and post it in this thread.

Do not fix anything yet unless you know what you are doing. This is a powerful tool that can crash the computer if used improperly.

Please download SmitFraudFix from this link http://siri.urz.free.fr/Fix/Smitfra... Then extract the contents to your desktop.
!!!! Only run option #1 as runing the other options on an uninfected computer will damage the desktop.!!!!
Open the "SmitfraudFix" folder and double-click "smitfraudfix.cmd"
Select option #1 - Search by typing 1 and press "Enter"; a text file will appear, which lists infected files (if present).
Please copy/paste the content of that report into your next reply.
Note : process.exe is detected by some antivirus programs (AntiVir, Dr.Web, Kaspersky) as a "RiskTool"; it is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

I have the same problem, downloaded this Anti-Executable from Faraonics, and now I cannot uninstall it. Here's the report of SmitFraudFix, maybe you can help me. I have located the file, but it won't let itself deleted:
