I was on here a few weeks ago for help getting rid of pop ups in my browser. I ran malwarebytes until it was clean, then did a full scan with superantispyware and got only tracking cookies. Now I am getting popups again some of the time. I have run malwarebytes several times since. Sometimes it comes up with ~20-30 vundo things and sometimes completely clean, but the problems always come back. Currently, when I run malware bytes, I get three entries and they dont seem to go away. My malwarebytes is up to date.

I also have a problem with a RUNDLL error when my computer boots. It says: Error loading C:\WINDOWS\system32\jenorebu.dll. The specified module could not be found.


Here is the current malwarebytes log:

It's not unusual to receive such an error when "booting up" after using anti-virus and other security scanning tools to remove malware infection.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to the file(s) in the error message.
  • Right-click on the entry and choose delete.
  • Reboot your computer and see if the startup error returns.
Now rescan again with MBAM but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for updates 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.

Sorry for not getting to this sooner. It turned out that when I started my computer the rundll error was gone so I didnt do the autoruns thing. (I hope thats ok).


I did the full MBAM scan and got the log below. Unfortunately, as I was coming to post this, I got the AntiVirus2009 popup so the problem isn't gone.

I'm having trouble with the program. Following the directions, I get a prompt to download the free trial version immediately after I click start. If I click the X like the instructions say, the entire program exits and I can never get to the main menu.

The program version I got was 5.00 if anything might have changed...?

They must have released a new version. The scanning instructions appear to be the same. I tested and did get the prompt to download the Full version Free Trial. I clicked the X to close the window and it did close but the express scan continued and finished. Are you sure you did not click the X on the scanning module instead of the new window that opened with the prompt?

The problem is that when the trial dialog pops up, the scanning module just disappears. When I click the X the whole program disappears (closes I guess because the tooltip for hovering on the X says Exit). The scanning module never comes back. I had someone else follow the directions on my computer and they got the same result so I don't think I'm reading it wrong. I'm really appreciating your help, though.

Using these instructions:

Scan with Dr.Web CureIt as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? <--I GET TO HERE AND GET THE TRIAL DIALOG
Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window. <--THEN I DO THIS AND IT EXITS
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
...



EDIT:
I tried running launch.exe not in safe mode and got one of those send error report/don't send crash dialogs saying "setup.exe has encountered a probelm and needs to close." I never get the crash dialog in safe mode. This might explain why I never see a request to run setup.exe by the security program even though I do get a confirm run request for launch.exe.

EDIT2:
I ran Dr Web Cure It myself fine on another computer that is not infected. I didn't encounter any of the Dr Web Cure It problems I described above on the non-infected computer.

I did the ATF Cleaner and the SAS scan. The SAS log is below. I think that this may have gotten it because there used to be a strange IE browser add-in that I couldn't disable before and I don't see it now. Sometimes the popups didn't happen right away so I'm going to have to wait and see, but things look good so far.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Tips to protect yourself against malware and reduce the potential for re-infection:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid gaming sites, underground web pages, pirated software, crack sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Unfortunately its back. I havent been using my computer in the last day and IE was only sitting with a window open to this thread. But there was a popup ad in the background and the strange browser helper object is back, but with a different random name.

Details on the IE add-on (if it helps):

Tools->Manage Add-Ons->Enable or Disable Add-Ons
Showing Add-Ons currently loaded in IE
Name: {40B8022F-1D69-49AE-BFCE-F927677B1A84}
Publisher: <BLANK>
Stastus: Enabled
Type: Browser Helper Object
File: gehotimi.dll

If I try to disable it, it appears enabled next time I open the add-ons window.

Your last MBAM log indicates you are using an outdated database. Please update it through the program's interface (preferable way) or manually download the updates and just double-click on mbam-rules.exe to install. Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot 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 infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is a hidden piece of malware which has not been detected that protects files (which have been detected) and registry keys so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

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 Psuedo 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.

If after 5 days you still have received no response, then post a link to your log in the thread titled "Post in this thread when you haven't received an answer in five days.".

I was sent here from the "Am I Infected" forum after my vundo infection kept resurfacing. I was instructed to follow the HJT preperation thread, but dds.scr is not running on my computer. It runs on another uninfected computer just fine when I tried that. The dds.scr window appears but is blank when I run it. I never get the welcome/instruction text and no scan runs (I left it for ~1 hour).

Symptoms of my Vundo infection:
>Popups -- AntiVirus 2009 ad and others
>strange Browser Helper Object in IE7 add-ons -- can't be disabled, randomly named dll
>Automatic Updates are always disabled in services.msc when I boot up

What I've tried:
>MBAM scans -- quick and full, finds things but they come back
>Dr Web Cure It -- FAILED to run in safe or normal mode
>SuperAntiSpyware -- full scan in safe mode after ATF Cleaner, seemed to be successful for a few hours, but problems came back and I visited no questionable sites and barely used my computer

What do I do now that dds.scr won't run properly?
