Hi there!

I had quite a lot of nasty things on my pc these days... I managed to get ride of most thanks to all the tips I found on your site, but one is anoying me like mad!!! :blink: backdoor.rbot.f ,Bitdefender blocks it, but impossible to move it, delete it or clean it... even in safe mode.

I already did things like hijackthis, cclean, avg antispy, etc.

Please help :whistling:

You may want to print this or save it to notepad as we will go to safe mode.

Fix these with HiJackThis – mark them, close IE, click fix checked

O23 - Service: Print Spooler Service (ayboaoesj) - Unknown owner - C:\WINDOWS\System32\nlkfev78995292.exe (file missing)

O23 - Service: Network helper Service (MSDisk) - Unknown owner - C:\WINDOWS\System32\irdvxc.exe" /service (file missing)

O23 - Service: Microsoft sdk core (sdk) - Unknown owner - C:\WINDOWS\lsass.exe (file missing)
====================
Click Start > Run > and type in:

services.msc

Click OK.

In the services window find this exact name

Print Spooler Service

Rightclick and choose "Properties". Beside "Startup Type" in the dropdown menu select "Disabled". On the "General" tab under "Service Status" click the "Stop" button to stop the service. Click Apply then OK. File-Exit the Services utility.

Repeat for - Network helper Service - : Microsoft sdk core
=====================
DownLoad http://www.downloads...org/KillBox.zip or
http://www.thespykil...les/killbox.exe

Restart your computer into safe mode now. (Tapping F8 at the first black screen) Perform the following steps in safe mode:

Double-click on Killbox.exe to run it. Now put a tick by Standard File Kill. In the "Full Path of File to Delete" box, copy and paste each of the following lines one at a time then click on the button that has the red circle with the X in the middle after you enter each file. It will ask for confimation to delete the file. Click Yes. Continue with that same procedure until you have copied and pasted all of these in the "Paste Full Path of File to Delete" box.

C:\WINDOWS\lsass.exe
C:\WINDOWS\System32\irdvxc.exe
C:\WINDOWS\System32\nlkfev78995292.exe

Note: It is possible that Killbox will tell you that one or more files do not exist. If that happens, just continue on with all the files. Be sure you don't miss any.

START – RUN – type in %temp% - OK - Edit – Select all – File – Delete

Delete everything in the C:\Windows\Temp folder or C:\WINNT\temp

Not all temp files will delete and that is normal
Empty the recycle bin
Boot and post a new log from normal NOT safe mode

Please give feedback on what worked/didn’t work and the current status of your system

Thanks for your prompt reply!!!! :whistling:

So apparently everything is ok with services, print spooler and network helper.
But sdk core is still there...

Killbox didn't find any of the 3 files
C:\WINDOWS\lsass.exe
C:\WINDOWS\System32\irdvxc.exe
C:\WINDOWS\System32\nlkfev78995292.exe

Now my pc seems to be ok, even if it takes ages to start... but i will let it run for a bit to see if i get this backdoor.rbot again.

Thanks for your help
