I have been looking around at plenty of manual removal methods, etc. on this site and others and I finally broke down and got an account on this site so I could ask for help.

The problem is as the title suggests. I have tried running my McAfee Security Scan and it will come up with two (last night during the full scan it gave me four) Dekstop.ini trojans that can't be removed, and MBAM will quarantine some files, but won't fully remove the issue.

I have run TDSSKiller and it quarantines some of the issues but it says there's an issue with C:\Windows\System32\services.exe and that it's infected. I try to run the "Cure" process and it tells me "There are unprocessed malware objects", and gives me the option to either close the program or run another scan, which will repeat the process to no avail.

I want to run ComboFix (unless there is another way), but I don't want to do it without someone's help, which I would greatly appreciate. I already have TDSSKiller, MBRCheck, ComboFix, (all installed to my desktop) and MalwareBytesAntiMalware on my system, just as a heads up. As I said, I've run a full virus scan and TDSSKiller, and I've also run a full MBAM scan.

Thanks in advance for assisting me.


That is the transcript from my original post(which I posted in the wrong location initially). I ran the steps in the preparation guide and was told to run ComboFix, but I don't want to until someone looks over these logs to let me know what I should definitely do next, since every post has told me to wait to run ComboFix. Although, if someone can quick confirm that ComboFix is the next step, I will run it today and post a ComboFix log.

I want to make it clear I have not run ComboFix yet and will not until someone says so. I really don't want to mess up my computer before Thursday (I have a presentation).

Thanks in advance for the assistance.

Below I have included a number of recommendations for how to protect your computer against malware infections.

  • It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article
    Strong passwords: How to create and use them
    Then consider a password keeper, to keep all your passwords safe. KeePass is a small utility that allows you to manage all your passwords.

  • Keep Windows updated by regularly checking their website at :
    http://windowsupdate.microsoft.com/
    This will ensure your computer has always the latest security updates available installed on your computer.

  • Make Internet Explorer more secure
    • Click Start > Run
    • Type Inetcpl.cpl & click OK
    • Click on the Security tab
    • Click Reset all zones to default level
    • Make sure the Internet Zone is selected & Click Custom level
    • In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
    • Next Click OK, then Apply button and then OK to exit the Internet Properties page.

  • Download TFC to your desktop
    • Close any open windows.
    • Double click the TFC icon to run the program
    • TFC will close all open programs itself in order to run,
    • Click the Start button to begin the process.
    • Allow TFC to run uninterrupted.
    • The program should not take long to finish it's job
    • Once its finished it should automatically reboot your machine,
    • if it doesn't, manually reboot to ensure a complete clean
    It's normal after running TFC cleaner that the PC will be slower to boot the first time.

  • WOT, Web of Trust, warns you about risky websites that try to scam visitors, deliver malware or send spam. Protect your computer against online threats by using WOT as your front-line layer of protection when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites:
    • Green to go
    • Yellow for caution
    • Red to stop
    WOT has an addon available for both Firefox and IE

  • Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.

  • ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.

  • In light of your recent issue, I'm sure you'd like to avoid any future infections. Please take a look at these well written articles:
    PC Safety and Security--What Do I Need?.
  • Simple and easy ways to keep your computer safe and secure on the Internet

Thank you for your patience, and performing all of the procedures requested.

Please respond one last time so we can consider the thread resolved and close it, thank-you.
