Hi,

Here's my details..

I recently visited a not so ordinary website and downloaded an .exe file that contained a trojan virus.
When i executed the file, it vanished and my antivirus software (provided by Rogers in Canada) detected a
trojan virus (win32.trojan.tdss.axqv) after almost 7 hours of scanning. It was located
in C:\WINDOWDS\Temp\0000657c.sys.THe virus was quarantined and I had it deleted.

However, when I tried to access malwarebytes.org, the site was blocked, and could not update my malwarebytes
anti-malware software. I have started to receive annoying popups on my laptop. Have managed to update definitions in malwarebytes using a clean computer and the process is scanning currently. Am using my desktop computer for accessing the internet and my laptop has been disconnected for a while now.

I am sorry beforehand to skip reading any removal guides available in this forum, because I am looking for a proper course of action from a team of professionals on a one to one basis

I thank you in advance for the help extended

Intial Computer Specs..

OS: WIndows XP Professional SP3
Intel Pentium M process 1.60GHz
Rogers Online Protection with Anti-Virus and Anti-Spyware

Update: I am running the current version of Malwarebytes running and just finished scanning. Have deleted files...

Hello and welcome. Let's do these next. Post back the new logsand an update on how it's runnning.

From your regular user account..

.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.

Hello Boopme,

First and foremost , thank you for your response on short notice.

Now for some feedback...

1) I have followed your instructions on my laptop while I was offline.
Had to transfer installers for ATF and SUPER Anti-Spyware from my usb drive to my infected
laptop. Is this procedure alright? I have scanned my usb drives for any threats but it's clean.
I have even reformatted the USB drive just to be sure.(Being extra cautious!).

2) Ran both ATF and SUPER in safe mode without any problem( offline). I signed in as user
with administrator privileges which I hope is alright. Done with SUPER and
currently running Malwarebytes with updated definitions as I type.


Some concerns..

3) I have noticed some strange folders like for example...
a) C:\Documents and Settings\All Users\JohnC which I did not create and is still present.
:thumbsup: Suspicious looking text file with strange characters in C:\Temp\1cb\syscheck.txt

4) After running ATF, I have noticed something strange in the results window..
The file size for internet explorer was way too large(some 8-10 digit MB) compared
to those with firefox (192,...KB). Strange because I never use IE and have been always
using firefox except when downloading windows updates. Looks like our hacker is
targetting IE and downloading stuff..I can't be sure.


5) Could there be infected files that are hidden( like a sleeper virus) and
waiting to feed on my laptop once I go online?

Here are the logs as requested..

Hello, these infections download additional malware on the machine by connecting to a remote server. You can do this and see what shows or we can also post a DDS log in the Malware forum.

Second thought let's post the DDS log..
We need a deeper look,please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic from step 9.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/302776/trojan-virus-detected-and-quarantined-virus-nametrojanwin32tdssaxqv/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
