Trojan : Win32/AgentBypass.gen!K and Dr Web crashing

I am infected with Trojan : Win32/AgentBypass.gen!K. I saw one of the other threads in this forum regarding how Dr Web is able to remove Trojan : Win32/AgentBypass.gen!K on Windows Vista. I tried to run Dr Web to run the express scan but it crashed immediately and the window saying setup.exe has encountered a problem and windows is trying to figure out a solution pops up. Can somebody please guide me regarding what could be wrong here? I am not even able to launch Dr Web launch.exe to run the scan as advised in the other thread. Yes I am running the setup.exe as Administrator.

Let's first try Mbam
--------------------

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.

• 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 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 and exit MBAM.

Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to [b]allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

I downloaded and installed MBAM as instructed and performed a quick scan (not complete scan). But MBAM did not detect any malware I have posted the resulting log below here.

Please reboot the computer
Open MBAM and click Update tab, select Check for Updates,when done
click Scanner tab,select FULL scan
After scan click Remove Selected, Post new scan log for review
If nothing is detected, we'll move on to other scans
Do you use Windows Defender ?

I rebooted and ran a full scan of MBAM on all my drives. Even this failed to detect any malicious software I have pasted the log below.

Yes I am using windows defender. It is telling me that I have been infected by this Trojan every time i boot my laptop. Thanks...

It appears Dr. Web is the way to go
Uninstall Dr. Web and download it again from here:
http://www.freedrweb.com/cureit/
If you can, do it in Safemode w/networking
If it won't run, try renaming the .exe to .bmp or .bin

I downloaded Dr. Web again and tried to install it in safe mode without networking. But even here it gives the same problem. It starts and then i select setup. Then it gives the pop up that says

"setup.exe has stopped working

A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available"

I tried renaming launch.exe to launch.bin and launch.bmp. But then it tries to open them in VLC Player and windows photo gallery. How do I make the .bin or .bmp to execute instead of opening in some other application? I am not able to install Dr. Web itself.

All I can suggest:

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.

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 have posted a new topic in the Hijack This Forum. The link to that is pasted below. Thanks for your help so far...

Hello arjuns,

Thanks for posting back with the link.

Now that your log is posted, 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.

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