I was infected with the Security Tool program which kept telling me to purchase bogus antivirus software. I was able to remove the program, but my computer remains severly debilitated. Several Windows applications have disappeared (Internet Explorer, Wordpad, Notepad, Windows Help and Support), icons remain but programs won't open; Mozilla won't open without crashing; my browser is repeately taken over and legit links take me to commercial websites rather than the intended destination; ctrl+alt+delete does not work.
I have tried to run various Anti-malware programs but very few of them will work - Malwarebytes won't run (various runtime errors), rkill and dds both give me error messages ('An unknown error occured. The program will be terminated.'), Rootrepeal just crashes and automatically reboots my computer each time I attempt to run it. I am able to run IObit Security 360, but each time it runs it finds and supposedly deletes all of the same things including something called lowsec, and various cookies and registry keys which it calls backdoor trojans.
I have no idea where to go from here! I would appreciated any help you can give me, thank you!

Hello it appears you have the Zbot or Zeus malware/trojan. It's function is to steal online banking details.
Please note: 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:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
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.


Our first step to removal is to try an online scan.
Please run the F-Secure Online Scanner
Note: This Scanner is for Internet Explorer Only!
Follow the Instruction here for installation.
Accept the License Agreement.
Once the ActiveX installs,Click Full System Scan
Once the download completes, the scan will begin automatically.
The scan will take some time to finish, so please be patient.
When the scan completes, click the Automatic cleaning (recommended) button.
Click the Show Report button and Copy&Paste the entire report in your next reply.

Thanks for the reply. I did notice that a window popped up asking me to 'verify' my information when I went to the Wachovia website. That was not a subtle attempt to get my info but I'm sure there's more going on hidden from my view. Thanks for all of the advice, I'll contact my banks and credit card companies.

The results from the F-Secure Online Scanner are below; 27 malware found, 25 cleaned, 2 not cleaned

No, last night rkill and mbam were both still giving me the same error messages. When I repeatedly reinstalled mbam the .exe file disappeared as soon as I installed it. Internet Security 2010 appeared out of nowhere and I was trying to manually remove those files when the computer crashed and will not reboot. Guess it's time to reformat and reinstall the OS. I'll revisit the links you posted in your first reply, thanks for the help

Seriously, the computer won't even boot up now. I get the Windows welcome screen, blue screen, reboot - in an endless loop. Anyhow, I was never able to run dds in the first place. As I mentioned in my original post, I kept getting an error message: 'Error!' 'An unknown error occurred. The program will be terminated.' I have no option now but to reformat and reinstall the OS

As I mentioned in post 3. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.

==============================

2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe/.scr/.htm/.html/.xml/.zip/.rar files as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Download Belarc Advisor - builds a detailed profile of your installed software and hardware, including Microsoft Hotfixes, and displays the results in your Web browser.
Run it and then print out the results, they may be handy.

Since we don't know exactly which infections we're dealing with here, we should take some precautions before we attempt to move files from the infected machine. Run the following on your clean computer, and make sure you insert your flash drives at the prompt.
Download and Run FlashDisinfector

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.
