I'm afraid that I have taken a few steps backward as of last night. The problem has gotten worse. When I turn the computer on, it goes into a "reboot loop". I have been fast enough to be able to log out as the normal user and log on as a "guest" user which stops it from the "reboot loop" and have been able to use the computer normally, except the guest user does not have access to any of the things that I need to have access to. While logged in under the guest user, I have tried to run some virus scans. They start to run, but then get so far and reboots my computer, thus sending it into the "reboot loop" once again unless I am fast enough to log out as the normal user, and log in under the guest.

As stated before, I am unable to bring up the www.bleepingcomputer.com website from the computer. I am currently using a public computer.

What OS (Win 2K, XPsp1, XPsp2, Vista) are you using?

Can you boot into "Safe Mode"? If so, try running your scans from there.

I'm sorry for not letting you know about the Operating System. I am running Microsoft XP service Pack 2. I tried booting in safe mode last night, and was still unable to run a scan without it rebooting the computer. I can double check this tonight. Also, some of the scans that I have tried to use are Ad-Aware, A-Squared, CA Virus Scan, CCleaner, and SpyBot. I think there is one more, I just can't remember it right now. All of these will not allow me to upgrade them from the internet either, so I'm using an outdated definition list that is a couple of weeks old on some, and a couple of months old on others.

Please download ATF Cleaner by Atribune & save it to your desktop. alternate download link DO NOT use yet.
Please 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".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.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 "Custom Scan", then 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 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.

Okay, I've done all that you have asked in the last post, although it wasn't easy. I found last night that being able to pull up your website was impossible. It kept giving me a page that said that it could not be found. When I received your last post, I copied down the web address of the two files that I needed to download, and I couldn't even pull those webpages up either. I found that it would give me this same error page for all websites that had to do with software. I had to go to a public computer last night and download the files to a floppy disk and then bring it home in order to copy it over to the computer. I was successful in getting the two scans done. After rebooting my computer, I am now able to access your site from the infected computer. Although I know I'm not finished yet with the cleaning, I am having a pop up window come up that just will not go away. It looks like genuine Microsoft message that says that "The system has recovered from a serious erorr. The log of the error has been created and wants me to send this report to Microsoft." I keep clicking on the "don't send" key, but it keeps popping up. Let me know what to do next.

Here is the log file that you asked for from Dr. Web.....

Good work. However, please note that clbdriver.sys is related to a rootkit component. Rootkits are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, 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. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the rootkit has been removed the computer is now secure. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read "When should I re-format? How should I reinstall?", "Help: I Got Hacked. Now What Do I Do?" and "Reformatting the computer or troubleshooting; which is best?".

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Let me know how you wish to proceed.

Sorry for taking so long on emailing back. I was taking some time to process what I need to do next. What a disappointment when things like this happen. To make a long story short, I'm thinking we will need to reformat the drive, and then reinstall the operating system. In reading one of the articles, it says that once you install the OS, then you shouldn't have it connected to the internet until after you have installed the updates. I need to buy a copy of the operating system, since we do not have the discs. Do you think I need to just buy this directly from Microsoft since they should have the most current copy, or from a software store that might have had it on their shelf for a while?

That's the decision I would have made if this were my system.

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 by wiping your drive, reformatting, and performing a clean install of the OS removes everything and is the safest action.

In case you need help with this, please review "How to partition and format a hard disk in Windows XP".

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

Reformatting a hard disk deletes all data. If you decide to reformat, you should back up all your important documents, data files and photos. The safest practice is not to backup any .exe files because they may be infected. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive. Don't forget you will have to go to Microsoft Update and apply all Windows security patches.

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

Do you think I need to just buy this directly from Microsoft since they should have the most current copy, or from a software store

As long as you go to a reputable store to buy your disk, you should be fine. And that would be faster that buying from Microsoft through the mail unless you pay extra for speedy delivery.
