Hi, there,

I recently downloaded some software and installed it. It was not what I thought, but a virus installer. It was suposed to be a PDA application, but it wasn't.

Now, after reading lots of pages and posts (several in this forum) I know that I have an infection. I sent some suspicious files to VirusTotal and I have the report of being infected with Vundo and Monder. My AVG informed before of a SHuer2 trojan, and I did some things tying to clean by my self.

I will travel to aplace where I am not sure to have internet connection, so, If there was some one ready to help me disinfect my comp, I will be gratefull.

I have logged in as administrator in safe mode and scanned the laptop and some infections were removed.

I passed the Hijackthis and got some strange things that I fixed with HJT (just 3 items)

I carefully examined the AVG and the HJT logs and came out with some files in my SYSTEM32 directory. I sent some of them to Virus Total and got the info I revealed above.

I have a file called sarapoga.dll as well as some unknown and strangely named files (exes and dlls) that were suspicious to me.
they are:
# Archivo C:\WINDOWS2\system32\convirus_system32.rar

Welcome to BC.

Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

In addition, I can now access my register with regedit, though I still cannot open the task manager (I have tried several versions that exist spreaded in the Windows directories (servicepacks, old versions, out of date versions...)

Thanks in advance, again, for your time and thoughtfullness.

Rescan again with Malwarebytes Anti-Malware (Quick Scan) in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Some malware infections target and place restrictions in the registry and how files are executed. To fix these restrictions, try the following:

Please download sreng2.zip and save it to your Desktop.
  • Create a new folder on your hard drive called Sreng2 (C:\Sreng2) and extract (unzip) the file there. (click here if you're not sure how to do this. Vista users refer to this link.)
  • Open the folder and double-click on SREngLdr.EXE to launch it.
  • Select System Repair from the left pane.
  • Click on Windows Shell/IE.
  • Put a check mark in the box next to Enable using Task Manager in Windows...
  • Click Repair.
  • The Status should now show Ok.
  • Exit SREng and reboot the computer.

Ok, I'll do all that you say.

I will travel next friday to a place that I don't know if I would have internet connection. Thus, I should try to fix this problem before I leave. I appreciate your effort and speed in helpping me.

Hi, quietman (john wayne),

No. I expected to do so, but I couldn´t. I realized that I didn't reboot my computr after Malwarebytes, so I rebooted it and tried again with the Sreng2. Checked the apropriate boxes and the programs stated OK. But things are the same with TaskManager.

There is a boot items button that shows a line like this:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe] <IFEO[taskmgr.exe]><0> [N/A]

I did a scan with Sreng2 and obtained a log file, that, if you wish, I can send to you.


I am a bit familiar with the registry and can look for things or change things, should you think this is better.

No way to activate TaskManager.
I can Windows-update, and everything seems normal but this taskmanager issue.

Also, something that I didn't mention before, At the beginning of knowing that I had a virus I noticed that Internet explorer (a program that I never use) opened by itself several windows, aparently innocent, but that I didn´t open. Even less in IE.

At the reboot of my computer, a messagebox appeared telling me that printcfg..exe had not passed the verification and asked me if I really wanted to install prtincfg.exe. It sounded suspicious to me because I had never had to install this software alone. So I checked No and went to delete the file printcfg.exe.

This is recognized also by Sreng2.

Have you installed sysinternals Process Explorer and checked the "Option" to "Replace Task Manager"? If so, be aware that Process Explorer replaces Task Manager by adding a value named "Debugger" in the registry. If that's the case, launch the program, go to Options and untick it.

If you don't use Process Explorer, have you installed or used another utilitiy similar to it? Process Hacker, KillProcess, DTaskManager and Glarysoft Process Manager to name a few, are similar programs that offer an option to replace Task Manager as the default. If you don't use any of these programs, then the registry key may have been altered by malware.

I recently installed it, but I haven´t noticed untill now that I couldnˇt access Task Manager.

Whenever I try to run the task manager, it complains saying that windows can´t find Task manager or one f its components.

Let me check Process Explorer...
It was unchecked

I am now in California and I use to live in Spain. I didn´t take the original Windows CD with me, so I cannot replace or restore my system.

żany suggestion?

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

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. 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.

Hello JASH,

Now that you have a log posted here: http://www.bleepingcomputer.com/forums/t/223494/monder-vundo-roguelink-bho-sheur2-altoghether/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY 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 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. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
