Hi guys, so I have been doing EVERYTHING off my work computer since my home laptop had this mishap but I've decided it's time to see if I can fix this thing. 

 

My computer with the problem has Windows Vista operating system.  When I start it up, it only goes to a black screen with a blinking cursor.  I cannot press F8 to go into Safe Mode.  I can only press F2 or F12.  Something interesting to point out was that before this happened it seemed like I was getting a random radio broadcast that would start playing on my computer.  I had no idea where this was coming from and didn't know how to stop it. It did not seem to be linked to any browser.

 

Thanks for your help.  Willing to follow whatever instructions I need.  I did have a problem before and believe I created the ability to startup Ubuntu (sp?) from a usb drive which I still have.  Don't know if that will help.

 

Thanks,

Steve

Hello uscsteve,

We apologize for not getting to your topic earlier!! Would you still like assistance with this issue?

If so, could you please tell me exactly what happens when the machine boots? Do you see the Windows splash screen, or does it go directly to the black screen with blinking cursor?

Again, we apologize for the delay!

Thank you.  Been waiting patiently.  When the computer boots up it shows the DELL screen.  In the top right it says F2 = Setup, F12 = Boot Menu and there is a bar in the lower middle of the screen that progresses by loading white to the right.  This screen appears for a few seconds before it progresses to the black screen with the white cursor.

 

Looking forward to your response.  Thank you!

:warrior:
Your computer is probably infected by virus. You should check computer for virus firstly, and then consider other situations.

Yes, I have come here because I think that my computer is infected by a virus.  If I could check using software I could but I can't even startup in safe mode.  That is why I'm looking for advise from the experts.

Hello again steve,

Just to let you know, I have moved this topic to the Malware Removal Logs forum where it will stay, so that we could get the proper logs posted.

(Sorry katy brit, but you won't be able to respond here now that I've moved the topic.)

==============================

The random radio broadcast you heard is indeed a sign of a rootkit, and we will be exploring that as well. :)

Okay, let's get started!

Let's see if we can get a recovery disk created--instructions for that are included in the below steps (the second green "Note:"):

On a clean machine, please download Farbar Recovery Scan Tool and save it to a flash drive.
Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.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.
  • Select US as the keyboard 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.
Note: In case you can not enter System Recovery Options by using F8 method, you can use Windows installation disc, or make a repair disc. Any Windows installation disc or a repair disc made on another computer can be used.
To make a repair disk on Windows 7 consult: http://www.sevenforums.com/tutorials/2083-system-repair-disc-create.html




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.
  • Select US as the keyboard 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.
==========

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

==========


Once in the 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 (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 copy and paste it to your reply.

Hi, I cannot get anywhere by pressing F8.  I'm a little confused about creating a system repair disc.  I don't have a Windows Installation disc.  The infected computer has Windows Vista and my work computer has Windows 7.  Do I create a Windows Vista repair disc on the Windows 7 computer?

 

Sorry!

Hello again,

Sorry to confuse...you'll be creating the repair disc from your working computer (Windows 7), to use on the non-booting machine (Vista). Skip the F8 instructions, and use the Installation disk instructions with the repair disc you created.

Does that help?

Created the repaid disc on my Windows 7 computer.  I went to setup so it would boot from CD/DVD drive first.  The computer goes to the Dell screen and then to a screen that says in the top left "Press any key to boot from CD or DVD. . . . . _"   The underscore is blinking.  I press keys but nothing happens.  I've tried 3 times.  When I continue to press keys they just give me a high-pitched beep.  :(

Hello again,

 

Sometimes the disk doesn't create properly, I would try re-creating the disk and try again. If that won't work on your system, then are you able to borrow a Vista Installation disc from a family member/friend/colleague?

 

If that simply isn't possible, then we could try other methods. Do you have a USB device we could format and use?

I created the recovery disc and it worked this time.  When I selected "Windows Vista" as the operating system I wanted to use it told me "This version of System Recovery Options is not compatible with the version of Windows you are trying to repair.  Try using a recovery disc that is compatible with this version of Windows."

 

I do have a USB drive that I can use.  Last time I think I had problems that this stage.  I had installed ubuntu onto a USB drive.

Hello again,

 

Okay, we may not be able to use the recovery disc, so please see if you could borrow a disc from someone else. In the meantime, I'll get other options ready.

The disc from someone else would need to be a Windows Vista installation disk, correct?

Yes any Vista Installation disc will do, to enter the system recovery options.

I'm honestly not sure I'll be able to get a Vista installation disk.  It seems most people don't have this O/S anymore.
