Toshiba Laptop P4 2.6Ghz, 512mb, 160Gb HD, 32mb DDR VRAM.
Windows XP Home SP2, IE 7.


I just purchased Chief Architect Home Design & Landscape program which I installed on my Quad Core Desktop PC due to its high system requirements. Because I normally only use that PC for my CCTV system I do not use it for Internet surfing.

I decided to go to the program developers website to check what additional symbol libraries were available. Their libraries were like their program very expensive, however, they also gave links to 3rd party providers so I thought I'd check those out too.

My laptop had a fresh install of XP & everything else I needed in mid January, with AVG 9 set to update & scan daily + MBAM which I ran every 3 days. Up till this point everything seemed to run fine.

On going to the first 3rd party link there was no problem but it did not seem to give me a clear idea of what was available or the cost. I then clicked on the second link and the site loaded for a fraction of a second before rapidly loading multiple Ad Sites that I could not close down until I eventually had to pull the network cable out of the laptop, wait a few seconds and close IE down completely.

I then ran AVG which found nothing, I ran MBAM and it found various Trojans, Malware & infected Registry entries which it reported all as "Quarantined & Deleted Successfully" at the end of its scan.

On rebooting, I found that my Firewall was turned off & my CPU was running at a constant 100%. I have run MBAM again with a fresh install of MBAM with updates in Normal Mode & Safe Mode both in User Account and Administrator Account. It makes no difference, on every reboot the Firewall is turned off, the CPU runs at 100% constant and the registry entries for Malware.Trace & Backdoor.Bot are back.

Can anyone tell me how I can clear this as I cannot afford to do another Full system re-install at this time for various reasons.

TIA

Keith

Hi Keith let's take another look please.
Do you do any Financials on this PC.

Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
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.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.
Please ask any needed questions,post logs and Let us know how the PC is running now.

Hi boopme

The answer to the first question is no I do not do any Financial work on my laptop other than access my bank account online, which I will not do while I have any hint of this infection, but the laptop is the DDNS link to my CCTV System which is currently being accessed by the local Police Drugs Squad to gather evidence at present, which is why I would like to get the laptop clean without having to do a complete system wipe and Re-Install again.

I have followed everything step by step as you instructed.

After rebooting again normally there is no change. The Firewall is still off, CPU running at 100% and if I manually check the Registry against the last MBAM Log, all entries that are reported as "Quarantined & Deleted Successfully" are still present in the registry.

The entries shown listed above as "Security.Hijack" all have the same information in the right hand window as follows:

Name Debugger

Type REG_SZ

Data ZASRAKOMONDOHUI31338.EXE


Does that give you any indication of the problem ?

I Look forward to your reply Thanks

Hello, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

That infection you see is a nasty variant of the TDSSSERV rootkit component. Rootkits, backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit


As you do not want to reformat we nee to move to another forum and use specialized tools to remove this safely.
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.

Hi boopme

Thanks for getting me to this point, I always deleted all browsing history, cookies and passwords on completion of any internet use as a matter of normal practice. As soon as this infection occurred I disconnected the laptop from the internet and deleted all history, cookies, passwords and temp files using both internet options and CCleaner.

The laptop has not been used for connection to the internet since other than to update the programs you have advised me to use, and that will continue till I recieve the allclear from the MRT who is advising me.

I am now going to proceed with the Prep Guide steps as instructed by yourself, I already have all the possible scanners/programs recommended by Bleeping Computer downloaded onto a USB stick but will not use anything until instructed by the MRT.

When I carry out Step 9 I will put a link to this thread in the text box for the MRT to view if required and I will also post back here when complete so that this thread may also be closed down.

Thanks again

Keith

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/304641/infected-with-trojanwin32agent2zasrakomondohui31338exe/ 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.
