Trojan-Spy and Trojan.Downloader problems

Unread postby Andrew » June 25th, 2007, 6:17 am

Hi,
My virus protection program (and some other software that I have downloaded) has over the past week informed me that my computer has had the following malware (though not all at once):

Packed.Win.Tibs.aj
Trojan-Spy.Win.32.Banker.qu
Trojan.Downloader.Win32.VB.axs
Trojan.Downloader.CashDeluxe (C:\Windows\system32\msorcl32.exe and C:\Windows\system32\wmvds32.dll)

At one point the computer clock was set back 4 years.... I also noticed that, when I went to the Hotmail sign-in page, Interned Explorer connected briefly with some "secure.footprint.net/…./…." site (without showing the actual page). Is my computer talking to someone behind my back? I changed password and stopped accessing Hotmail from my own computer.

I have tried different software to deal with this. My Internet provider’s virus programme (Securitoo) deleted most viruses/Trojans, but some reappeared once or twice after that. SpyBot only detected 5 DSO exploits (which I asked to have fixed, but for every new scan they were there again…). Trojan Hunter didn't find anything. Neither did Windows Defender.

Lately the computer seems quite OK (because I don't connect with Hotmail – and the secure.footprint site – anymore?...), but the Trojan.Downloader.CashDeluxe, which was detected by PCTools' Spyware Doctor, is still there (at least Spyware Doctor says it is…). (I used the trial version. It would require the paid version to remove it and I don’t want to send credit card details over a connection I don't trust….)

Could you please help me to check if my computer is clean, and, if not, tell me how to deal with it? I am not very keen on reinstalling Windows XP.

Here is a fresh HJT log:

Andrew,
----------------------------------------------------
I am sorry to be the bearer of bad news but unfortunately, as you suspected, you have a very dangerous infection, with "backdoor" capabilities.
This gives remote intruders complete control of your computer, which can include logging key strokes, stealing information, etc.

You are strongly advised to do the following immediately:
  • Disconnect the infected computer from the internet and from any networked computers until the computer can be cleaned.
  • Call all of your banks, credit card companies, financial institutions and inform them that you may be a victim of identity theft and to put a watch on your accounts or change all your account numbers.
  • From a clean computer, change *ALL* of your online passwords -- for ISP login, email, banks, financial accounts, PayPal, eBay, online companies, and any online forums or groups you belong to.
Do NOT change passwords or do any transactions while using the infected computer because the attacker will get the new passwords and transaction information.

Because of the infection's backdoor functionality, the basic security of your PC is very likely compromised, and there is no way to be sure it can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action is to reformat and reinstall the Windows Operating System.
The reason for this is that the infection can make undetectable changes to your security settings in order to re-install itself after the machine is "cleaned" and reconnected to the internet.
If you do not have the resources to reinstall your OS and would like me to attempt to clean your machine, I will be happy to do so. This is your choice to make.

To help you make a more informed decision, you may wish to read the following articles:
Should you have any questions, please feel free to ask.
Please let me know if you choose to Reformat.

If you want to attempt to clean your computer instead of Reformatting and Re-Installing XP, please begin here:
-----------------------------------------------------------
Set Your Computer to Show All Files
  1. Click Start.
  2. Click My Computer.
  3. Select the Tools menu and click Folder Options.
  4. Select the View Tab.
  5. Under the Hidden files and folders heading, select Show hidden files and folders.
  6. Uncheck Hide protected operating system files (recommended).
  7. Click Yes to confirm.
  8. Uncheck the Hide file extensions for known file types.
  9. Click OK.
-----------------------------------------------------------
Using My Computer, navigate to your HiJackThis folder here.
C:\Program Files\HijackThis\
Double click to show the files. Select View, Details
Right-click HijackThis.exe, choose Rename, and rename it myscanner.exe
------------------------------------------------------------
Please download VundoFix.exe to your desktop.
  • Double-click VundoFix.exe to run it.
  • Click the Scan for Vundo button.
  • Once it's done scanning, click the Remove Vundo button.
  • You will receive a prompt asking if you want to remove the files, click YES
  • Once you click yes, your desktop will go blank as it starts removing Vundo.
  • When completed, it will prompt that it will reboot your computer, click OK.
  • Please post the contents of C:\vundofix.txt and a new Log from myscanner.exe

Note: It is possible that VundoFix will encounter a file it cannot remove.
In that case, VundoFix will run on reboot. Simply follow the above instructions starting from "Click the Scan for Vundo button." when VundoFix appears at reboot.

I will follow your advice and reformat/reinstall.

Many thanks for your help.

askey127,

Just one question before I reinstall:

Do I dare to backup my recent Word, Excel, music- and video-editing files before I reformat and use them afterwards, or is there a risk that they too are badly infected?

It is OK to back up all your DATA files like .doc, .xls, .txt, etc. files before you reformat. Just be sure to scan all those backups with your antivirus before copying them back into their respective folders.
Otherwise, just be sure you have your antivirus installer file saved so you can install it offline BEFORE you plug in the Internet cable.- then when you do plug in the Internet, immediately go to the Microsoft site and get ALL the critical updates, followed by a visit to your Antivirus home site to update your AV.

If you don't have an antivirus installer file or CD, you can download one of these free ones to save before you reformat. This is best to do from a clean computer.
