Think I have a trojan

Hello

I have been having a few problems for a few days. I don't know if they are related, but either way I think I may have a virus or trojan.

A couple of days ago after visiting a specific site I started to get error messages of two types. One would pop up seemingly at random and tell me spoolsv.exe had to shut down. I did a search at processlibrary.com and this is apparently either to do with the windows printer manager or it is malware. I have never had a printer set up on this computer so that was a bit of a worry. I would also get errors whenever I closed a program, saying that a memory address could not be accessed (sorry I don't remember the exact wording).

I ran both my spyware programs - I use Spybot S&D and Malwarebyte's Anti-Malware - and neither of them found anything. In the end I did a system restore and it seemed to solve the problem.

So what I have now is probably unrelated but I thought it best to mention the above.


I ran a search with both programs yesterday because I had been downloading things and always search after downloading anything. Both programs found something called virtumonde.atr and other things, mainly registry entries or changes. Also when I restarted the computer, a DOS window briefly flashed up on the desktop then disappeared, as if something was running which I had never seen before, and something was disabling all my Windows security such as the firewall. I told the programs to remove the problems, re-scanned and it found some of them again. I repeated this process a few times and now it has stopped displaying any findings so I thought it had worked.

Now I have re-enabled the windows security stuff. The problem I have now is when I search for things in Google, some of the time when I click a search result it redirects me to the wrong location. Invariably this is some page with lots of other search results, but it is a different page each time.

It is not a big problem but anything like that going on worries me because I'm not sure what else is happening to my PC that I can't see.


I have just run Spybot S&D again and it found nothing. I am currently in the process of running a full scan with Malwarebyte's Anti-Malware, and so far it has found nothing, but it's not done yet.


Sorry for rambling, I just don't know much about this stuff and wanted to cover everything because I don't know which bits are important.

Thanks


(edit: MBAM completed its scan and found nothing)

Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer. Another techinique is for the process to alter the registry and add itself as a Startup program so that it can run automatically each time the computer is booted. A file's properties may give a clue to identifying it. Right-click on the file, choose Properties and examine the General and Version tabs.

Tools to investigate running processes and gather additional information to identify them and resolve problems:These tools will provide information about each process, CPU usage, file description and its path location If you right-click on a file and select properties, you will see more details.

Please download ATF Cleaner by Atribune & save it to your desktop. alternate download link
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Please download and scan with Dr.Web CureIt.
Follow these Instructions for scanning with Dr.WebCureIt in "safe mode".
If you cannot boot into safe mode, then perform your scan in normal mode. Be aware, this scan could take a long time to complete.
-- Post the log in your next reply.

Please download Malwarebytes Anti-Malware 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.

Thank you for your response.

I ran the ATF cleaner as instructed.
I ran Dr Web Cure It. It didn't find anything. I wasn't able to save a log, I assume because it had nothing to report.
I ran MBAM and it didn't find anything either. Here is the log:

How is your computer running now? Are there any more reports/signs of infection?

I am still getting redirected when I use Google. It doesn't happen every time but obviously still isn't right.
Also occasionally when click a link instead of loading the correct website I will get a message about updating some kind of media player which I have never installed, and it looks like it's starting to download files. Every time this has happened so far I've closed the browser asap. If it happens again I will make a note of the exact wording but again it doesn't happen 100% of the time.

Other than that nothing seems to be wrong. It is weird though.

This issue will require further investigation. Before that can be done you will need you to create and post a DDS/HijackThis log.

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
Hello soapy_margherita,

Now that you have a log post posted here: http://www.bleepingcomputer.com/forums/t/219857/google-redirect-problem-which-isnt-found-by-spybot-mbam/ 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.

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