Just last night I copied a file from a USB of my apartment mate and I noticed that there was something wrong the way the explorer is showing. I inspect my system and found two instances of services.msc in windows task manager [press ctrl + shift + esc] one run by my currently logged user and one by SYSTEM. I searched my computer for instances of a virus or a worm, etc and I found an abnormal entries, files on my computer/registry: ITEM A +HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version\Winlogon under Shell string value there is an abnormal appended string c:\windows\system32\keyboard\services.exe, normal is explorer.exe +c:\documents and settings\all users\application data\fearghus\lsass.exe +C:\Documents and Settings\All Users\Application Data\Microsoft\USB2.0\usb-hi.exe +C:\Documents and Settings\All Users\Application Data\Fearghus\lsass.exe +C:\Documents and Settings\All Users\Start Menu\Programs\Startup\kbdrv16.com I successfully removed the following by: 1.) starting my windows in safe mode with command prompt (press F8 repeatedly while OS is booting) 2.) deleting the entry in the registry a.) start regedit, in the command prompt type regedit b.) navigate here HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version\Winlogon c.) change the value of the Shell key to just explorer.exe 3.) navigate to c:\documents and settings\all users\application data\ >cd c:\documents and settings\all users\application data\ a.) delete the fearghus directory >rd /s fearghus 4.) navigate to C:\Documents and Settings\All Users\Application Data\Microsoft\ >cd C:\Documents and Settings\All Users\Application Data\Microsoft\ a.) delete USB2.0 directory >rd /s USB2.0 5.) remove the entry on the Startup a.) navigate to C:\Documents and Settings\All Users\Start Menu\Programs\Startup\kbdrv16.com b.) execute delete file command >del kbdrv16.com 6.) restart your machine and boot normally, inspect the registry the Shell key should just contain explorer.exe, and all the files specified in ITEM A should be gone by now. That's all. This procedure works for me :D.

I was able to remove it after reading your blog. I used Process Explorer and Autoruns in safe mode. Disabled system restore then I used Process Explorer first, killed the tree running false microsoft lsass.exe then it came up with a count down that will shut off the system in a minute. I rushed deleting all the usb-hi.exe and fearghus and kbdrv16.com entries using Autoruns. Restart. Now its clear.

If you ever encounter that shut off message again just type this in the command prompt

shutdown -a

If you ever encounter that shutdown message again just type this in command.exe

Hi, did you restart your pc in safe mode? If it was the same virus I had, I'm sure it doesn't run in that mode.

jampochi said...

hello sir, can you please email me what sd and cd means in your instructions? everytime i try to delete fearghus, it says application is running. :(

Thanks a lot. :)

For your information:

1.) To successfully delete the trojan file, your pc should be in safe mode.

2.) As for cd and rd, they are commands to be executed in the shell command line. cd stands for change directory; while rd means remove directory.

3.) To execute these commands you should run cmd in Start->Run type cmd and press enter.

my computer screen went black after acquiring those viruses? does it happen to you also? thanks

Fortunately, it doesn't. I've just notice those weird files and processes that runs on my pc.

If you've boot successfully try scanning your system with:

spybot
malwarebytes
comodo registry/system scanner

Note: These softwares are free.

Or try booting in safe mode. See if it works.
