Can someone please advise me on what to do? Upon starting my computer yesterday, I got an alert from BOClean that this trojan was found in C:\Windows\System32\Drivers\KMXAGENT.SYS. The alert stated that the trojan was shut down, removed, and registry cleaned. After I closed the alert, Spybot asked me about accepting the registry change, deleting values to these items: NDSTray.exe, TFncky, and sbusbAudCtrl. Believing this was what BOClean had done I accepted the change.

Less than a minute later a windows installer dialog box appeared, preparing to install something it said was from Wal-Mart Music Downloads Store. I was not at the site, didn't have a browser open, and it didn't seem legitimate to me, so when the firewall asked about allowing it I refused it. The installer kept on and on popping up and I kept having to close it. Eventually I opened the Control Panel and removed it.

I had a bad feeling that there's more problems, but I ran a Norton full system scan, as well as a Spybot scan and neither turned up anything but tracking cookies. When I shut down afterward, a message came up saying Access violation, followed by some numbers, but it flashed so briefly I couldn't get them down...then another message "ccSyCHst.exe application error...again it was gone before I could get it all.

Today when I started up, another alert about this trojan horse, still in this same file. This time BOClean said it removed the trojan but the file still existed and did I want it removed, to which I said yes. Then Spybot asked about allowing the registry deletion to ISUSPM at C:\Program files\Common Files\Install Shield, and I agreed. Later after doing some reading here I registered and attempted to post, but got a message about the forum being down temporarily for some work. Just now when I started the computer back up to try again to post, before anything had even loaded up, a windows installer box was trying to install something, which I cancelled. This is way beyond me, and it's really scary to know that even with several layers of protection, and "safe' surfing something still got through.

I hope someone can help. I'm running XP Home Edition with Service Pack 2, and IE7. Thanks!

Hello Galen S. and welcome to BC :thumbsup:

Let's try a scan with MalwareBytes.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 and you may be prompted to restart your computer. (see Note below)
  • 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 will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Please post the MalwareBytes log in your next reply.

I was not prompted to reboot. I messed up and forgot to close the Spyware Tea Timer and it asked immediately afterward about allowing two changes in the registry, which I did allow. Was that right or did I just undo everything?

Hello,this is a Rootkit type of malware. Rootkits are not actually the malware but the system or device by which other malware can be hidden.

You should proceed to posting a HiJackThis log as these infections require a thorough removal. Please proceed to and follow the instructions in this tutorial "Preparation Guide For Use Before Posting A Hijackthis Log".
If there are points in there you have done or have trouble doing skip that and move on. At Step 9 you will greate the Log.
Please post that log into this forum HijackThis Logs and Malware Removal and NOT here thank you.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Hello Galen S.,

Now that you have your log posted here: http://www.bleepingcomputer.com/forums/t/141059/rtkt-vantir-infection/ 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.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

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

Orange Blossom :thumbsup:
