Hi and welcome to Major Geeks, mgulsby!

For 32-bit (x86) systems download Farbar Recovery Scan Tool and save it to a flash drive.
For 64-bit (x64) systems download Farbar Recovery Scan Tool x64 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:

On the System Recovery Options menu you will get the following options:

• 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 this log to your next reply. (How to attach)

 

I have done what you have said. Attached is the file.

Attached is fixlist.txt

• Save fixlist.txt to your flash drive.
• You should now have both fixlist.txt and FRST64.exe on your flash drive.

Now re-enter System Recovery Options.
Run FRST64 and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt).
Please attach this to your next message. (How to attach)

Now attempt to boot normally.

If you were able to boot successfully and still need help removing malware, it is recommended that you go through this thread next: How to Remove TrojanOS/Alureon.A

 

It has booted up prefect that time with no problems. Attached is the log that you wanted.

 

Looks good. Let me know if you need additional help.
