My son caught somethng bad on his desk top.  I restarted in safe mode and ran virus scanners from an external clean drive.  Remove about 30 issues.  I restarted it and goes to log in screen, after loggin in it goes blank.  If I hit cntrl alt delete, I can get the red screen options, but that is it.  Any choice goes back to the blank screen including the task manager option.  Tried to restart in safe mode again and nothing or at least same thing happens with blank screen. At this point I don't want to touch it any further as I know that can make matters worse.
 
I do not know what he did with the disc (I fgure that is the first question you will ask, no I don't have it at the moment)
 
AAAhhhh  Grrrr
 
What now?

:welcome:

 

Lets give it a try. You will need a flashdrive.

 

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.

Plug the flash drive into the infected PC.

  • If you are using Windows 8 consult How to use the Windows 8 System Recovery Environment Command Prompt to enter System Recovery Command prompt.

    If you are using Vista or Windows 7 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.
  • 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.

Thank you for everything thus far, but I am running into two things:

 

Please note, I tried to hit the Shift  F8 to access safe mode again, (when I started all this before my original posting) got the login screen, tried to log in, and the screen went blank.  So I cannot access the comand prompt as instructed by this link:

 

If you are using Windows 8 consult How to use the Windows 8 System Recovery Environment Command Prompt to enter System Recovery Command prompt.

 

 

Second: The link for the system recovery disc is for windows 7, I searched that site but I am not seeing one for Windows 8.

 

 

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

 

So since I can not get to the command prompt and need the installation disc info:

 

1. Will the Windows 7 installation disc work?  I am thinkng it won't, but you know better then me and I just want to clarify before I proceed.

 

2. Since I do not have an actual "disc" at the moment, can I put the installation disc information on the flash drive with the Farbar and still work the same?

 

Thank you.

Method 1.  Hangs on red screen saying Please wait  for about 20 minutes

2. Can't get to charm bar
3. Can't get to command prompt
4. Do not have Windows 8 installation Media disc
5. Do not have Windows 8 Recovery drive
6. Can not choose boot option for system recovery.
 
To add to the fun, PC Performer (which I know is fake an yet another virus)  just popped up on the black/blank screen and is running.

Try the AVG Rescue CD:

"AVG rescue CD is basically a portable version of AVG anti-virus, which runs on linux distribution as bootable CD or bootable USB flash drive. This Rescue CD is equipped with AVG Antivirus , AVG Anti Spyware and some administrator recovery tool.


You can scan and remove computer virus without booting operating system first. It is suitable for recovering MS Windows and Linux operating systems (FAT32 and NTFS file systems) from virus and spyware attack. Meanwhile, Administrator toolset on AVG rescue disk are Windows Registry editor, a TestDisk utility for data recovering and lost partitions, a file browser for navigating folders, and a Ping tool for basic network diagnostics."

Please Note: Windows does not have to load for this scanner to work.

You can download  AVG rescue CD HERE.
It's also located on ThisPage, make sure you download the .iso file.

Here's how it goes:

Install the program, and follow the next set of steps.

After you install Active@ ISO Burner, put a blank cd-r in your burner and double click on the AVG Rescue CD.iso you downloaded and Active@ ISO Burner should automatically open up.....now click BURN.

The program is very easy to use, you'll just be pressing Enter most of the time but here's how it goes:

1. After the rescue cd is made, boot-up the sick computer, put the rescue cd in and then restart it.
Note: In order to do so, the computer must be set to boot from the CD first. For information on how to do that....click HERE.
2. At the Boot Menu: Choose AVG Rescue CD (1) and press Enter

3. Let it load, at the "Disclaimer Screen"... just choose I agree or not and press Enter

4. At the "Update Screen", choose Yes and press Enter

Next screen, Choose Update from Internet and press Enter

5. At the "Update Priority Configuration" window, choose Priority 2 Virus Database Update and press Enter

6. Let it update and when finished, Press any key to continue

7. You end up back at the "Update Screen", choose Return and press Enter

8. Your at the "Main Menu" screen, choose Scan, press Enter

9. "Scan Type Menu", choose "Volumes Scan - Selected Volumes" and press Enter

10. "Scan Volumes", choose "OK" and press Enter

12. "Run Scan", choose "Yes" and press Enter

13. When scan is complete, Press any key to continue

14. "Info screen", choose "OK" and press Enter

15. To see the scan report, select "Report File" and press Enter
Please look over the list as some files can be crucial for the Windows system and deleting them can make it inoperative, if  in your not sure please Google the file or files.

16. "Scan Results Menu", use the up and down keys and choose "Select - Handle single or groups of infected files", press Enter
Go through the files and choose to Rename the infected file, don't choose Delete!
This is important....Rename<---

17. Read the "Warning Screen", "Yes" and Enter

18. Back to "Scan Results Menu", choose "Back or Return" to get to the "Main Menu" and then choose ---->Reboot System
Don't forget to take out the rescue cd.

19. All the malware files will be renamed to "_INFECTED.arl", to find all of these files....
Go to Start > Search > All Files and Folders > type "_INFECTED.arl" and click search.
  Example: malware.exe would be renamed to malware.exe_infected.arl

20. Note: If you find the cd doesn't load, it's most likely do to a bad download or bad burn, download the file again and burn it at a slower speed.

I can't access anything past the red log in screen.

 

At this point I am thinking all I can do is try to get a hold of a Windows 8 recovery disc, unless there is some way to factory reset it.
