Removal of system32\jkkli.exe trojan

I'm new to the forums and found a thread discussing how to remove the system32/jkkli.exe trojan. It sounded like this required a very specific evaluation of which files were infected, etc, so I'm hoping someone can help me out. It's my son's PC that's infected. He's off to college and said to do "whatever" with his PC, so I was just checking it out, found a fan that had stopped working, a bunch of drivers that were out of date, and the annoying thing is that the computer just randomly restarts. I thought this might have been an overheating problem, but it's still doing it after I replaced the fan. During startup there's message about the jkkli.exe was not able to load and that's when I learned this is a nasty trojan horse that inserts into many different programs that load during startup. I'd much appreciate any help in getting rid of this thing.

Thanks in advance.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

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.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra 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.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Thanks for the reply and sorry for the delay in getting back to you. I've now subscribed to my topic and will be notified when replies come in as you suggested.

I'm currently at work and will download the Malwarebytes tool when I get home. Thanks for your patience and I greatly appreciate the help!

Your very welcome.

Sorry for the delay in getting back on this. So I downloaded Malwarebytes, changed the name as you suggested to zztoy, had to change the extension from .exe to .bat to get it to load, performed the Full Scan, performed Remove Selected and here is the log.

Upon restarting I still got the original message that the jkkli.exe file can't be found. Looks like there's still more work to do?

Ok, next:

Please run ATF and SAS:
Credits to Boopme

Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note 2: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

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 or Opera browser click that browser 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.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

I really appreciate the help. Here's the SUPERAntiSpyware Scan Log. If it makes any difference, I had to use "msconfig" to get the computer into Safe-Mode.
Also, after reboot in Normal mode I still got the jkkli.exe message.

Thanks again for the continuing help.

Have you tried disabling jkkli.exe from the startup using msconfig?

Excellent recommendation CP!! That seems to have worked.

Here's what I did to remove jkkli.exe which was appearing during startup.
1. Go to "Run" and type msconfig to get to the System Configuration Utility.
2. Select the Startup tab.
3. Scroll until the jkkli.exe entry is found and uncheck it.
4. Close the System Configuration Utility.
5. Open the Registry Editor (Go to "Run" and type regedit).
6. Uncheck everything except for "Keys" and then search for "msconfig". (This gets you to the correct directory.)
7. Open the "startupreg" folder and delete the jkkli.exe entry.
8. Restart and check the System Configuration Utility to ensure that jkkli.exe has been deleted.

Thanks again for all your help Computer Pro!!!!

So no other problems now?
