hi there friends!! I am Mohammed Al-shatti, 24 years of age. I am not a technical person and thats why I ended here to learn. I have a problem with my laptop. It has a virus that hides the original file and replaces it with a .exe file. I have important files in my hard drive so reformatting is not an option. At first I survived using it by just using the folder view option and I was able to view the hidden original file. But lately this method didnt work. My laptop restarted and when I logged in, there is just a black screen. I search online and found a temporary solution by creating a new task called explorer.exe. It worked but the icons on my screen were gone, its just plain texts. Also, when I try to open registry and command prompt, the laptop restarts. And my browser would automatically open and display a website which I will be attaching below. I uninstalled my anti virus a month ago and I think this is my big mistake. :(

For this reason, I seek the help of smart and expert people like the ones in this forum for help. :help:

I hope to learn from my mistakes and in the future, if I will have the chance, I will also help people from the things that I will be learning her :happy:
:thumbsup:
Thank you in advance guys.. :thumbsup:

Hello bodom13 and welcome to my office here at G2G! :)

My nick is maliprog and I'll be your technical support on this issue. Before we start please read my notes carefully:

NOTES:
  • Malware removal is NOT instantaneous, most infections require several courses of action to completely eradicate.
  • Absence of symptoms does not always mean the computer is clean
  • Kindly follow my instructions in the order posted. Order is crucial in cleaning process.
  • Please DO NOT run any scans or fix on your own without my direction.
  • Please read all of my response through at least once before attempting to follow the procedures described.
  • If there's anything you don't understand or isn't totally clear, please come back to me for clarification.
  • Please do not attach any log files to your replies unless I specifically ask you. Instead please copy and paste it to include the log in your reply.
  • You must reply within 3 days or your topic will be closed



We will need clean PC and USB memory to download and transfer tools to infected PC. First we need to disinfect your USB memory so you can transfer files and not get infected. You will do first step on clean PC. After that download all tool on clean PC and run it as described on infected PC.

Step 1

Do this on the clean computer:

  • 1 - Flash Drive Disinfector
    Download Flash_Disinfector.exe by sUBs from here and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.

    Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you run it. Don't delete this folder...it will help protect your drives from future infection.

Step 2

We need to disable malware processes on your system first
  • Download TheKiller to your Desktop
  • Note that TheKiller is renamed as explorer.exe
  • Run it by double click (If running Vista or Windows 7, right click on it and select "Run as an Administrator")
  • Press OK button after program finish
  • Do not restart your system after this step
NOTE: If malware blocks TheKiller from running please try to run it several more times

Step 3

Download OTL to your Desktop

  • Double click on the icon to run it (If running Vista or Windows 7, right click on it and select "Run as an Administrator"). Make sure all other windows are closed and to let it run uninterrupted.
  • Under the Custom Scan/Fixes box paste this in

    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    explorer.exe
    winlogon.exe
    Userinit.exe
    svchost.exe
    services.exe
    /md5stop
    %systemroot%\*. /mp /s
    dir C:\ /S /A:L /C
    CREATERESTOREPOINT
    
  • Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
  • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them here for me.

Step 4

Please don't forget to include these items in your reply:

  • OTL log
  • OTL Extras log
It would be helpful if you could post each log in separate post using "Add Reply" button
