Recent Trojan

Unread postby crackalack » November 23rd, 2008, 1:34 pm

so recently i had a pretty bad trojan but i found it fairly quickly and i think i got most of it out, however when i checked security task manager 2 strange files with very high danger rating were found, i found the file and deleted it but for some reason it still shows up even after restarts.. im not sure if my computer is still infected or what, here are 2 pictures of the 2 files that im talking about (%1 and tuvukdsm.dll) they both say they monitor program starts so im not sure what to do with them, when i try to delete from registry of security task manager it says i need ordered version to do so because it has something to do with registry or drivers, or that it is just missing (when i try to click properties of the files)

Hi crackalack,

Open Notepad: press Start->Run, type notepad into the box and press OK
Select Format from the top menu and make sure Word Wrap is NOT checked.
Then, copy/paste the contents of the following code box into Notepad:
Code: Select all
@echo off
echo f | xcopy "C:\Windows\SysWow64\tuvukdsm.dll" "%userprofile%\desktop\tuvukdsm.dll" /h >> results.txt 2>>&1
echo f | xcopy "C:\Windows\System32\appdrvrem01.exe" "%userprofile%\desktop\appdrvrem01.exe.vir" /h >> results.txt 2>>&1
del %0 

Select File and Save as
Save it to your Desktop as "runme.bat" (you MUST type the quotes)
Locate runme.bat on your Desktop and double-click it.
A black box should open and close after a short time, this is normal.
Another text file should appear on your Desktop called results.txt, do not open it until the black box has closed.
Post the contents of this file in your next response.

One or two files may appear on your Desktop named tuvukdsm.dll and appdrvrem01.exe.vir, please upload both of these (if present) one at a time using the following instructions:

Please open this page in your browser:
http://www.bleepingcomputer.com/submit- ... channel=32
Fill in the link to topic field with a link to this topic
Click the Browse button, browse to and select the file from your Desktop, then press the Send File button, this will upload the file for analysis.


Download Autoruns to your Desktop
  • Double click autoruns.exe to start the program
  • Wait for it to finish scanning. When it has finished the status bar at the bottom will change from "Scanning..." to "Ready."
  • Select Options and select Verify Code Signatures to place a checkmark next to it.
  • Select Options again and select Hide Signed Microsoft Entries to check this option as well.
  • Click File -> Refresh
  • Once the new scan has finished, click File > Export As...
  • Save it to the desktop as autoruns.txt
  • Post the contents of autoruns.txt in your next response


Download RSIT by random/random to your Desktop (right-click the link, select Save Target As..., select your Desktop and press Save)

  • Double click RSIT.exe to start the program, and click Continue at the disclaimer screen.
  • When the scan is complete, two text files will open - log.txt <- this one will be maximized and info.txt <-this one will be minimized
  • Make sure Format->Word Wrap is unchecked
  • Copy (Ctrl+A then Ctrl+C) and paste (Ctrl+V) the contents of log.txt and info.txt in your reply


Once complete, please post the results.txt output, the autoruns.txt output and both RSIT logs, you won't need to produce a new HijackThis log as RSIT produces one for you.
