When you find that your computer will not boot, either due to malware or attempts to remove malware, please read through this tutorial. Maybe one of the options will work.

1. Make an 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.

AVG Rescue CD Guide-check here

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:

Download and install [email protected] ISO Burner
Click HERE for ISOBurner Instructions.
Install the program, and follow the next set of steps.

After you install [email protected] ISO Burner, put a blank cd-r in your burner and double click on the AVG Rescue CD.iso you downloaded and [email protected] 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

11. "Scan Options", 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.

Attention: VISTA, Windows 7, Windows 8 and Windows 10 users

Follow these steps to post in this forum:

Step One:

Open a new Topic in the forum. Never post on someone else's topic

Step two:

Clearly explain the symptoms of the computer and how you feel it became infected.

Step three:

In a working computer:

For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

Plug the flashdrive into the infected PC.

Boot to the Recovery Environment

  • Plug your USB Flash Drive in the infected computer
  • To enter the Recovery Environment with Windows Vista and Windows 7, follow the instructions below:
    • Restart the computer
    • Once you've seen your BIOS splashscreen (the computer manufacturer logo), tap the F8 key repeatedly until the Advanced Boot Options menu appears
    • Use the arrow keys to select Repair your computer, and press on Enter
    • Select your keyboard layout (US, French, etc.) and click on Next
    • Click on Command Prompt to open the command prompt
      Note: If you can't access the Recovery Environment using the F8 method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial on SevenForums.
  • To enter the Recovery Environment with Windows 8 or Windows 8.1, follow the instructions in this tutorial on EightForums
    Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial.

 

  • To enter the Recovery Environment with Windows 10, follow the instructions in this tutorial on TenForums
  • Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial on TenForums.

Once in the command prompt

  • In the command prompt, type notepad and press on Enter
  • Notepad will open. Click on the File menu and select Open
  • Click on Computer/This PC, find the letter for your USB Flash Drive, then close the window and Notepad
  • In the command prompt, type e:\frst.exe (for the x64 version, type e:\frst64.exe and press on Enter
  • Note: Replace the letter e with the drive letter of your USB Flash Drive
  • FRST will open
  • Click on Yes to accept the disclaimer
  • Click on the Scan button and wait for it to complete
  • A log called frst.txt will be saved on your USB Flash Drive. Post it in your next reply

If other scans are necessary, the helper will advise you how.
