I've been infected for about 3 days. I have installed symatec 2009 trial, which finds a generic, packed virus, but fails to remove it. I have also installed malwarebytes anti malware, and it finds more specific viruses(trojan.agent and trojan.tdss) and 'successfully' removes the .tdss but cannot delete the agent. It says that it has trojan.agent marked for deletion upon reboot but it fails there as well. I have downloaded sdfix, but I believe the trojan is preventing me from running it, as every time I start it up, the hour glass appears for a couple seconds and then nothing happens. Also, every time that malwarebytes removes the trojan, it reappears on the next scan even if I have not restarted.

Any ideas?

Hello and welcome. You have a TDDS infection.

One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, 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.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer 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 would be a reformat and reinstall of the OS. Please read these for more information:

When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

Ive had my computer disconnected from the internet as much as possible, except for when im downloading anti virus or posting. I would like to clean it because I really don't feel like formatting and I dont use this computer for anything really sensitive.

Ok let's do thes then. First some tips we may need.

Some types of malware will disable MBAM (MalwareBytes) and other security tools. If MBAM will not install, try renaming it.

Before saving any of your security programs, rename them first. For example, before you save Malwarebytes', rename it to something like MBblah.exe and then click on Save and save it to your desktop. Same thing after you install it. Before running it, rename the main executable file first
***
Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..


***
Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.
***
Open up command prompt, type in following commands:
XP >> click the Start menu at the lower-left of your computer's desktop and select "Run". Type cmd into the Run box and click "OK".
Vista >> click the Start menu at the lower-left of your computer's desktop and Type cmd in the search box.

regsvr32 mbamext.dll
regsvr32 ssubtmr6.dll
regsvr32 vbalsgrid6.ocx
regsvr32 zlib.dll

****

If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

***
Try this random renamer for MBAM
http://kixhelp.com/wr/files/mb/randmbam.exe
****


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


Run part 1 of S!Ri's SmitfraudFix
Please download SmitfraudFix

Double-click SmitfraudFix.exe
Select option #1 - Search by typing 1 and press "Enter"; a text file will appear, which lists infected files (if present).
Please copy/paste the content of that report into your next reply.

Note : process.exe is detected by some antivirus programs (AntiVir, Dr.Web, Kaspersky) as a "RiskTool"; it is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

Hello , I think 2 more scans and we are done..

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.



Rerun MBAM 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.
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Hey, sorry for my long repost time, Ive just gotten another computer to use. The problems on my computer had grown more numerous and I decided to just reformat. However, my computer began shutting down randomly, some times after 30 minutes some times after hours. Also, I will press my power button, and the computer will rev to life for just a split second and then shutdown again. I may have to press the button 20 or 30 times in succession to get it to start up. I want to format it, but it keeps shutting down in the middle of it. Any ideas?

Well if you are to reformat and I think it's a good idea here.. But i believe you also have a hardware issue. Perhaps the power supply. This is the cheapest part to replace.usually
You should start a topic in the XP forum first. We'll keep this here if needed.
