Either someone is playing a prank on you or you have a virus.

http://www.prevx.com/blog.asp?ID=31 maybe of help although I would look for more sources of solutions before downloading anything (not sure if the trial version of Prevx will even remove it).

Looks like you got hit with the new Vundo worm.

I'd like to ask for a HijackThis and a WinPatrol log if you could, then add them both to a zip file and attach the logs to your next post by going Advanced, then hitting Manage Attachments, then upload both of them. One file per zip, if you don't mind.

I figure I'll get this out of the way unless EvilFantasy doesn't need the logs.

You have been infected with Trojan.Xrupter!!! [LOL]
According to Symantec website, this trojan is a type of Vundo infections. The message is trying to sell you "FileFixProfessional" [aka: rogue decryption software "LOL"].
Here is the instruction [from Symantec]

Discovered: March 22, 2009
Updated: March 22, 2009 10:12:28 AM
Also Known As: Ransom-F [McAfee], Troj/Fakecor-A [Sophos]
Type: Trojan
Infection Length: 139,264 and 94,208 bytes
Systems Affected: Windows 98, Windows 95, Windows XP, Windows Me, Windows Vista, Windows NT, Windows Server 2003, Windows 2000

Removal using the Trojan.Xrupter Removal Tool
Symantec Security Response has developed a removal tool to clean the infections of XXrisknameXX. Use this removal tool first, as it is the easiest way to remove this threat.

Manual Removal

The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

1. Disable System Restore (Windows Me/XP).
2. Update the virus definitions.
3. Run a full system scan.
4. Delete any values added to the registry.

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.


For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

• How to disable or enable Windows Me System Restore
• How to turn off or turn on Windows XP System Restore

Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions

Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:

• Running LiveUpdate, which is the easiest way to obtain virus definitions.
  
  If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.
  
  If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.
• Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them.

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.


3. To run a full system scan

1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.
   
   For Norton AntiVirus consumer products: Read the document: How to configure Norton AntiVirus to scan all files.
   
   For Symantec AntiVirus Enterprise products: Read the document: How to verify that a Symantec Corporate antivirus product is set to scan all files.
2. Run a full system scan.
3. If any files are detected, follow the instructions displayed by your antivirus program.

Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.
After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

4. To delete the value from the registry

Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.

1. Click Start > Run.
2. Type regedit
3. Click OK.
   
   Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.
4. Navigate to and delete the following registry entries:
   
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\"AppInit_DLLs" = " %System%\fpfstb.dll"
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WOW\keyboard\advanced\"core_installed" = "1"
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WOW\keyboard\advanced\"id" = "[32 RANDOM CHARACTERS]"
5. Restore the following registry entry to its previous value, if required:
   
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\srservice\"Start" = "4"
6. Exit the Registry Editor.
   
   Note: If the risk creates or modifies registry subkeys or entries under HKEY_CURRENT_USER, it is possible that it created them for every user on the compromised computer. To ensure that all registry subkeys or entries are removed or restored, log on using each user account and check for any HKEY_CURRENT_USER items listed above.

You've been hijacked.

I'm sure this is a well spread problem, with many victims around the world.

Do you at least know what you ran to cause this? So you know to not run it again after your reformat ?


Do you plan on cutting your losses, or will you pay the ransom (if the hijackers email is still active that is)?


Hopefully there's some software out there which can save you.

Should this threat be move to the "spyware and virus" section

[abhishek.mulmule]

hi,
i tried the symantech removal tool for Xrupter trojan it didn't find any infection...
the problem still persists..
some spywares(windows live one care, SuperAntispyware) i tried didn't work either..

[YuMeng]

Your file get encrypted by ransomware. If your computer doesn't have any important files, you can reformat.
Or wait evilfantasy to post it out.

[ahashmi06]

That looks tough. Anyway try scanning your computer with Malwarebyte's Anti-Malware.

I hope this helps.



NOTE: According to this site (hxxp://www.securitystronghold.com/gates/win32.crypt.html), their product True Sword Threat Remover is able to remove the virus, but i doubt it.
I downloaded and scanned my computer with this tool and it detected my KIS2009 entry in the startup as malware(See Screenshot). Moreover it requires you to purchase it to remove the detected threats which i think are fake threats.
Do not download it.

I am not an expert in testing softwares, but this is what i think of the True Sword Threat Remover. If anyone wants to test it, they surely can.
