Alureon.E (virus)trojan

brato92,

Let’s take a look before Windows starts…

Need some info from you:
Do you have the Repair your computer option in the Advanced Boot Options menu?

To find out:
Restart the computer.
As soon as the BIOS is loaded begin tapping the F8 key until the Advanced Boot Options menu appears.
Is the Repair your computer option listed?

If you do not have the option, do you have your Windows installation CD/DVD available?

And last, do you have a USB pendrive available, and access to another computer that is not infected?

If you do have the Repair your Computer option...

You may want to print these instructions so you can have access to follow them. Also, you may want to read them once befor you apply them.

Please plug a USB pendrive into a clean computer.

Go to Start > Computer
Double-click Computer, and select the pendrive.
Right-click and select: Format
Press Start on the Format prompt.
Remove when done.


Next, download Farbar Recovery Scan Tool (64-bit version):
Farbar Recovery Scan Tool Download
Select the 64-bit download.
Save the program to the >> USB pendrive.

Also download List Parts 64-bit and save it to the USB pendrive.

brato92,

Please note Post #3 is edited to add ListParts.

Alureon.E operates by writing a cloaked partition which boots before the main system does. It generally does not show up under disk management. Since it is already running & in use, MSE cannot delete it.

The tool you are looking to use is GParted, a boot partition tool. This will confirm if you have a hidden partition. The partition is usually at the end of the drive & is between 1 - 10 MB. You can manually delete this partition, but you will have to re-establish the correct partition to be the boot sector.

Running TDSSKiller would be a good idea as it automates this process, & resets the boot sector back to it's rightful place.

Cottonball i have a problem: after i press Enter on 'Repair your computer' option under 'Boot Advanced Settings' (with USB stick inserted) nothing happens: the screen becomes black and that's all. After 3-4 minutes i have to reset the laptop because i think it is stuck. I've tried it for 2 times and nothing comes out.

I don't have an original Windows 7 DVD, because when i bought this laptop it came with Windows 7 installed. I found out (on Laptop's manual) that Windows Installation Kit (original) is on a hidden partition that i can't acces normally, but it can be accesed when i need to reinstall or repair the system.

I'm waiting for your advice.
