Hi,

I have a Dell Inspiron 1150 running WIN XP Pro. I have a bunch of trojan viruses that I can't delet. I'm running CA anti-virus software and it only caught and deleted a few viruses. I ran spybot and deleted about 50 spyware infections but I'm still having problems. I don't have access to the control panel anymore. I get an error that says the admin has denied access, blah, blah, blah. A few days before the problems becan I download NCH software suite. I wanted to convert some music files so I'm wondering if that caused my problem? I can't uninstall the program from the program list nor access the control panel to do so. My date/clock time is all messed up.

My windows installer will not work (message: "service could not be accessed") so I can't install a program to get rid of the viruses. Heres a sample list of the trojans currently residing on my PC:
SillyDl.PW trojan, Ldpinch.GQ trojan, Crupor! generic trojan, Clodpuntor.AA trojan, Eldycow.L trojan, SilentCaller. trojan, Serstroy.A trojan, Buzzit! generic worm,Vxidl trojan, Kalbto.A worm, MS05-002!exploit trojan, Shinwow.BG!ZIP trojan, ByteVerify!exploit trojan, Wonka.B trojan, IEPageSpoof trojan.

Help!

If your using Win XP or 2000, please print out and follow the generic instructions for using "SmitfraudFix".
(If you have downloaded SmitfraudFix previously, please delete that version and download it again as the tool is frequently updated!)
-- If the tool fails to launch from the Desktop, please move smitfraudFix.exe to the root of the system drive (usually C:\), and run it from there.

Please follow the the instructions for using Vundofix in BC's self-help tutorial: "How To Remove Vundo/Winfixer Infection".

After running VundoFix, a text file named vundofix.txt will have automatically been saved to the root of the system drive, usually at C:\vundofix.txt. Please copy & paste the contents of that text file into your next reply.

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.
Please download and install SUPERAntiSpyware Free

    • 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 a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

  • Launch the program and 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 and click "Next".

    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.

Quietman7,

Thank you for responding to my problem. Unfortunately, I'm unable to install SmitfraudFix.exe. I moved it to the root (C:\) but it still didn't open. Any other suggestions?

Thanks, :thumbsup:

Skip that step for now and continue with the rest of the instructions I provided.

Then download Dr.Web CureIt & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on cureit.exe to start the program. (ignore any prompts to update or check for a new version)
  • When the Dr.Web opens, an "Express Scan of your PC" notice will appear.
  • Under "Start the Express Scan Now", Click "OK" to start. This is a short scan that will scan the files currently running in memory and when something is found, click the Yes button when it asks you if you want to cure it.
  • Once the short scan has finished, Click Options > Change settings
  • Choose the "Scan tab" and UNcheck "Heuristic analysis"
  • Back at the main window, click "Select drives" (a red dot will show which drives have been chosen)
  • Then click the "Start/Stop Scanning" button (green arrow on the right) and the scan will start.
  • When done, a message will be displayed at the bottom advising if any viruses were found.
  • Click "Yes to all" if it asks if you want to cure/move the file.
  • When the scan has finished, look if you can see the icon next to the files found. If so, click it, then click the next icon right below and select "Move incurable".
    (This will move it to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if it can't be cured)
  • Next, in the Dr.Web CureIt menu on top, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop. (You can use Notepad to open/view the DrWeb.cvs report)
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply.

Well, I'm not having any luck! IE will not open, I still can't get to the control panel, registry, task manager, or other areas needed to clean my computer. These viruses have really harmed my PC. What do you suggest now?

quiteman7,

My computer problem was worst than I thought. My ISP told me that my PC has a botnet on it or is acting as an IRC server. A hacker got me! :thumbsup:

My only recourse is to reformat my hard drive. My only problem with that is my computer is rendered unusable. I cannot reach the DOS prompt, registry, task menu, properties, or control panel to reformat the harddrive. The OS installation disk that came with the PC is only used when no OS is present. Do you have any suggestions on how I can format my harddrive so that everything is wiped off and I can start fresh?

Thanks,

:flowers:

That's the decision I would have made if this were my system. Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to to gain unauthorized access to a computer and take control of it without your knowledge. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS.

Some types of malware can result in a system so badly damaged that a Repair Install will NOT help!. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over, reformatting the drive and performing a clean install of the OS removes everything and is the safest action.

For help with this, please review the following links:
"How to partition and format a hard disk in Windows XP"
"How do I reinstall and reformat Windows XP on my hard drive?"

These links include step by step instructions:
"Reformat & Clean Install Windows".
"XP Clean Install Interactive Setup".
"Clean Install Windows XP".

Also see "How to keep your Windows XP activation after clean install".

If you need additional assistance, you can start a new topic in the Windows XP Home and Professional forum.

Note: If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach.

Thank you quiteman7 for all the advice you gave me. I'll read over the links before attempting to clean my HD. If all else fails (or I goof up!), I could just buy a new HD right? :thumbsup:
