I recently got hit the fraud xp antivirus malware and I came to this forum to remove it from my PC and it worked now I have an error message that appears at startup saying

RUNDLL Error
C:\WINDOWS\uyijabow.dll
the specified module could not be found.

What does this mean?? (I'm assuming this is some sort of spyware that was remove by Malwarebytes)


2) There is an object that appears every time I run Malwarebytes irregardless of tha fact the MAL says that it was quarantined I have attached the log for review. Are these two related??

Hello.

That means the registry key pointing to that file is still there. Log on to the account that you get that error message and run the batch script below please.

Let's find it and then remove it. :thumbsup:

Create and Run batch script
  • Please create and execute the following batch script.
  • Copy the following into a notepad (Start>Run>"notepad"). Do not copy the word "code".
    @Echo off
    
    Echo [color=orange]------------------------HKCU\RUN KEY ----------------------------[/color] > C:\looking.txt
    
    reg query "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" >> C:\looking.txt
    
    Echo [color=orange]----------------------- HKLM\RUN KEY -----------------------------------[/color] >> C:\looking.txt
    
    reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" >> C:\looking.txt
    Notepad C:\looking.txt
    
    Del %0
  • Click File, then Save As... .
  • Click Desktop on the left.
  • Under the Save as type dropdown, select All Files.
  • In the box File Name, input peek.bat.
  • Hit OK.
When done properly, the icon should look like Posted Image for the .bat file.

Double click on peek.bat, and Black DOS window shall appear and then notepad will soon open. This is normal please do not panic. Once it's complete copy and paste the contents of notepad in your next reply.

Note: If you closed notepad accidentally, it can also be found at C:\looking.txt

With regards,
Extremeboy

Hello.

No need to PM me, I will be notified once a reply comes.

Peer-to-Peer Programs Warning

Your log shows that you are using so called peer-to-peer or file-sharing programs (in your case BitTorrent). These programs allow to share files between users as the name(s) suggest. In today's world cyber crime has come to an enormous dimension and any means is used to infect personal computers to make use of their stored data or machine power for further propagation of the malware files. A popular means is the use of file-sharing tools as a tremendous amount of prospective victims can be reached through it.

It is therefore possible to be infected by downloading manipulated files via peer-to-peer tools and thus suggested to be used with intense care. Some further readings on this subject, along the included links, are as follows: File-Sharing, otherwise known as Peer To Peer and Risks of File-Sharing Technology.

It is also important to note that sharing entertainment files and proprietary software infringes the copyright laws in many countries over the world and you are putting yourself at risk of being indicted through organizations watching over the rights of the authors of such files (i.e. the RIAA for music files, or the MPAA for movie files in the USA) or the authors of the files themselves.

Naturally there are also legal ways to use these services, such as downloading Linux distributions or office suites such as "Open Office."

It is your decision whether or not you wish to keep your program(s) but I suggest you remove it via add/remove. However, please refrain from using them until your computer has been declared clean.

Backup Registry with ERUNT

This tool will create a complete backup of your registry. A backup is created to ensure we have backup so encase anything goes wrong we can deal with it. Do not delete these backups until we are finished.
  • Please download erunt-setup.exe to your desktop.
  • Double click erunt-setup.exe. Follow the prompts and allow ERUNT to be installed with the settings at default. If you do not want a Desktop icon, feel free to uncheck that. When asked if you want to create an ERUNT entry in the startup folder, answer Yes. You can delete the installation file after use.
  • Erunt will open when the installation is finished. Check all items to be backed up in the default location and click OK.
You can find a complete guide to using the program here:
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt

How to Restore from the ERUNT Backup

Only restore from the backups if instructed to, or you need to do so. You need it if after doing something, your computer will only boot in Safe Mode and you are unable to contact us (or anyone else) for help by other means, or if your computer will not boot into Windows at all.

To restore if you can boot, navigate to C:\WINDOWS\erdnt, choose the folder with the most recent date, and double click ERDNT.EXE. Check all boxes in the restoration options.

To restore from the Recovery Console using the Windows CD:
  • Turn on your machine with the disk in the drive.
  • Type in the number of the Windows installation you want to repair (usually 1), then press Enter.
  • Type in the Administrator password (leave blank if you are unsure what it is or if you do not have one) and press Enter.
  • Type without quotes "cd erdnt" followed by Enter.
  • Type without quotes "dir" followed by Enter. This will list out the available folders, whose names are the date on which the backup was taken in (M)M-DD-YYYY format. Try the most recent dates first.
  • Type without quotes "cd **name of the folder**" followed by Enter.
  • Type without quotes "batch erdnt.con" followed by Enter.
  • Type without quotes "exit" followed by Enter.
  • Remove your CD from the drive and reboot your computer into the restored registry. If you still cannot boot, try again with an earlier restore date.


Create and Run Registry Script
  • Copy the following into a notepad (Start>Run>"notepad"). Do not copy the word "quote".

    REGEDIT4

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
    "Yzemefak"=-

  • Click File, then Save As... .
  • Click Desktop on the left.
  • Under the Save as type dropdown, select All Files.
  • In the box File Name, input fix.reg.
  • Hit OK.
When done properly, the icon should look like Posted Image for the .reg file.

Doube-click on fix.reg, you will get a warning saying something like: "do you wish to merge/add the following information to the registry?". Please say Yes.
Next you will get a confirmation telling you if it was merged sucessfully.

Tell me in your next reply if the reg script got merged sucessfully. Is the error message still there? Reboot to see.

With Regards,
Extremeboy
Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.

If I'm helping you and I don't reply within 48 hours please feel free to send me a PM.
