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 along with the SAS log report. Then continue as follows:

Please download SDFix by AndyManchesta and save it to your desktop.
alternate zipped version
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Double click SDFix.exe and it will extract the files to %systemdrive%
  • (this is the drive that contains the Windows Directory, typically C:\SDFix).
  • DO NOT use it 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".

Open the SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services or Registry Entries found then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts, the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load, the SDFix report will open on screen and also save a copy into the SDFix folder as Report.txt.
  • Copy and paste the contents of Report.txt in your next reply.
-- If this error message is displayed when running SDFix: "The command prompt has been disabled by your administrator. Press any key to continue..."
Please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\swreg IMPORT %systemdrive%\SDFix\apps\Enable_Command_Prompt.reg
Press Ok and then run SDFix again.

-- If the Command Prompt window flashes on then off again on XP or Win 2000, please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\FixPath.exe /Q
Reboot and then run SDFix again.

-- If SDFix still does not run, check the %comspec% variable. Right-click My Computer > click Properties > Advanced > Environment Variables and check that the ComSpec variable points to cmd.exe.
%SystemRoot%\system32\cmd.exe


Search for and delete the following file(s) in bold if they are present. You can use Windows Explorer to navigate to or use Windows Search feature > More advanced options to locate them.

Files:
C:\windows\system32\drivers folder\core.cache.dsk <- this file

When found right-click the file, choose delete and empty your recycle bin. If you get an error when deleting a file, right-click on it and check to see if the read only attribute is checked. If it is, uncheck it and try again. If that does not work, then open Task Manager, look for and kill the process if running, then delete the file. If you still have problems, then delete the file(s) in "Safe Mode".

--If you cannot see these files then Reconfigure Windows XP to show hidden files, folders. Double-click on My Computer, go to Tools > Folder Options and click on the View tab. Under Hidden Files and Folders, check "Show hidden files and Folders", uncheck "Hide Protected operating system Files (recommended)", uncheck "Hide file extensions for known file types", and hit Apply > OK. (Don't delete anything other than what I ask you to delete. After we are finished, follow the same procedure to hide these files and folders again to protect them from accidental deletion)

Your system is heavily infected. One or more of the identified infections is a backdoor Trojan. 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. Read the Danger: Remote Access Trojans.

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.

Although the backdoor Trojan has been 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 backdoor Trojan 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 reformat and reinstall the OS. Please read "When should I re-format?" 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. If you wish to proceed, please do the following.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install the current version of HJT in the proper location.) If using Windows Vista, be sure to Run As Administrator.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
