HELP! Trojan Elitebar, BackdoorDSNX, Downloader/MisleadApp

Unread postby arqa » May 7th, 2009, 9:36 pm

My PC runs Windows XP - Yesterday the Antivirus alerted me of 20 .tmp files located in C:\ WINDOWS\ TEMP infected with one of the following : Trojan Elitebar, Backdoor, Downloader/ Downloader MisleadApp...
Action Taken= Quarantine failed- Clean failed- Access denied.

Tried to find those files to delete them manually, but they weren't there...
So I run Hijackthis. Here's the log

Hello and welcome to Malware Removal.

My name is peku006 and I will be helping you to remove any infection(s) that you may have.
I will be giving you a series of instructions that need to be followed in the order in which I give them to you.

Please observe these rules while we work:

  • I f you don't know or understand something please don't hesitate to ask
  • Please DO NOT run any other tools or scans whilst I am helping you.
  • It is important that you reply to this thread. Do not start a new topic.
  • Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
  • Absence of symptoms does not mean that everything is clear.

1 - Download and Run ComboFix
We will begin with ComboFix.exe. Please visit this webpage for download links, and instructions for running the tool:

This tool is not a toy and not for everyday use.
ComboFix SHOULD NOT be used unless requested by a forum helper


Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
If you need help to disable your protection programs see here.

When finished, it will produce a log for you
Please include the C:\ComboFix.txt in your next reply for further review.

2 - Run Hijackthis
Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad

3 - Status Check
Please reply with

1. the ComboFix log(C:\ComboFix.txt)
2. a fresh HijackThis log

Thanks peku006

Hello peku006, thanks for the advice.
Prior to your response I deleted all internet temporary files. Once I got your message
I run Combofix & HJT. These are the logs:

"SecurityProviders"="msapsspc.dll, schannel.dll, digest.dll, msnsspc.dll"

Contents of the 'Scheduled Tasks' folder

C:\ComboFix2.txt ... 06-12-25 16:31
C:\ComboFix3.txt ... 06-12-25 16:22

Due to a lack of response, this topic is now closed.

If you still require help, please open a new thread in the Infected? Virus, malware, adware, ransomware, oh my! forum, include a fresh FRST log, and wait for a new helper.
