Hi guys,
I am working on this Laptop, its a Sony VAIO Windows 7.
The problem is it had a virus infection. Its DVD ROM wasn't working.
So I removed the hard disc, and scanned it from another PC (by connecting it via SATA casing).
The scan picked up and
Deleted Trojan program Trojan.Win32.VBKrypt.ctvi K:\Users\VAIO\heatoa.exe


After I put back the HDD and powered the laptop, all i got was a Black Screen + the cursor.
I tried to boot in SAFE MODE....nothing, still the same black screen and cursor
I tried
1) Reboot and press F8
2) Select "Repair my computer"
3) Select the keyboard layout and lanugage
4) When you reach system recovery tools, select System restore.
5) Select the restore point when it was working fine and restart the computer.

still nothing, system restore doesn't work either.
even HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon had cmd /k cmd.exe something as the shell, I changed this to explorer.exe but still nothing
I am truly lost, even SFC /SCANNOW when I tried this it says,"Another SFC is pending, restart and wait for it to complete before running again"- something of this sort.
Please help me

FWIW: I don't believe that scanning with an infected hard drive attached as secondary...allows for removal of items which may be in the registry on the infected drive. I believe that Windows will allow access to data/program files in such case, but does not allow changes to be made to the registry.

The black screen with cursor in upper left...historically indicates that the boot files have a problem.

I'll move this to the Am I Infected forum...and will also list on our Unbootable list. A BC Staff member trained in dealing with malware will attempt to assist you :).

Hello jdukze :)

  • I will be helping with your computer problems.
  • From this point on, it is very important that you refrain from doing anything else to your computer other than what I have requested of you.
  • I do not mind if you browse the web, do basic tasks, or even test to see if the problem(s) you are experiencing are still occurring with the computer while we are working together, but do not run any tools/fixes unless I or another helper from this thread has asked you to do so.
  • Remember that you came here for help, so allow us to help you :)
  • If something does not run, make a detailed note of what problems you encountered along the way (exact error messages are preferred), but continue onto the next steps until you reach the end of my post.
  • Always do the steps in the order they are listed in (left to right, top to bottom).
  • I prefer that you complete all the steps while you are in Normal Mode. However, I understand that sometimes this is not possible. If you are unsuccessful in getting a tool/fix to run from Normal Mode, but Safe Mode works, then use Safe Mode.
  • If you have a question about something, do not hesitate to ask.

Let's begin:


Posted Image Please download Farbar Recovery Scan Tool and save it to a flash drive.

Plug the flashdrive into the infected PC.

Enter System Recovery Options.

To enter System Recovery Options from the Advanced Boot Options:
  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  • Use the arrow keys to select the Repair your computer menu item.
  • Choose your language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.

To enter System Recovery Options by using Windows installation disc:

  • Insert the installation disc.
  • Restart your computer.
  • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  • Click Repair your computer.
  • Choose your language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account an click Next.
On the System Recovery Options menu you will get the following options:

  • Startup Repair
  • System Restore
  • Windows Complete PC Restore
  • Windows Memory Diagnostic Tool
  • Command Prompt

  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" and find your flash drive letter and close the notepad.
  • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
  • Note: Replace letter e with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) on the flash drive. Please attach or post the contents of this log to your next reply.

Just letting you know I've moved this topic to the Virus, Trojan, Spyware, and Malware Removal Logs forum,where it will stay.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
