I have Windows XP (Service Pack 3) and use Mozilla Firefox 3.6.10. I believe I have a virus on my PC as I am having intermittent problems with Google redirecting and trouble downloading combofix.exe from this site. I ran Kaspersky's TDSS Killer.exe which detected one Malicious Object--Rootkit.Win32.TDSS.tdl4--(\HardDisk0\MBR). Virus did not cure after reboot so quarantined it. Other things I have tried:
1) Microsoft Malicious Software Removal Tool (no infections found).
2) Hijack This (ran many times, performed suggested fixes, and saved logs).
3) Malwarebytes' Anti-Malware (quarantined Trojan Agent--C:\windows\system32\config\Systemprofile\Application Data\hotfix.exe).

Would appreciate help with this problem. Thanks.

Ok lets try this
Reboot into Safe Mode with Networking
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 with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.


>>>> Download this file and doubleclick on it to run it. Allow the information to be merged with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply
Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • 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.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • 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.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


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.

Rebooted into SafeMode with Networking. Downloaded the first file and double-clicked to run it. Allowed information to be merged with the registry. Downloaded rKill from Link 2. Double clicked but get error message as follows:
C:\Documents and Settings\Owner\Desktop\rkill.scr is not a valid Win32 application.

have you tried all the RKill's?

How about this one,
http://download.bleepingcomputer.com/grinler/rkill.scr

Please download exeHelper to your desktop.
Double-click on exeHelper.com to run the fix.
A black window should pop up, press any key to close once the fix is completed.
Post the contents of exehelperlog.txt (Will be created in the directory where you ran exeHelper.com, and should open at the end of the scan)

Since my post yesterday, new problems have developed. After not being able to download any of the five Rkill files, I rebooted in Safe Mode with Networking and tried the entire process again. This time the FixExe.reg file would not download providing the error message "Cannot import C:\Documents and Settings\Owner\Desktop\FixExe.reg: The specified file is not a registry script. You can only import binary registry files from within the registry editor."

New problem today was the brief appearance in the notification tray of the Automatic Updates yellow shield indicating 0% downloading. Might this be due to my many changes of the Automatic Updates service between Manual, Automatic, and Disabled as I have been trying to resolve yet another problem with scvhost.exe slowing down my PC.

I just tried downloading the file in your new post but it does not work. The download windows says "Canceled" and creates a 0 byte file. Is there some setting that I might have that is preventing me from downloading a file? Was the original successful run of the FixExe.reg file sufficient or has that file been compromised?

I don't have a second computer. Could I get one of the required rkill files (renamed) sent to me via email and then download to my PC?
