((Not sure where exactly to post this so if this is the wrong section, please delete))

Ok, so I screwed up ><

I've been having a lot of Avast shield pop ups for multiple trojans and rootkits.

Decided to try and run TDSS Killer to see if I had a rootkit. Using TDSS Killer, it identifies the Rootkit as "rootkit.boot.pihar.b" (but when that tries to cure, it says "Can't cure MBR. Write standard bootcode?" I selected yes.

I go to reboot normally and this is all I get:

Invalid Partition Table.

Yikes!!!!

Hi, Skiminims. Welcome to GTG. Let's help you out with your malware issue(s).

1. Preferably from a clean computer, please download the following: gparted-live-0.13.0-1.iso (124 MB)

When you have the .ISO file downloaded, you need to create a bootable disk or flash drive with it, using a clean PC to do that. The .ISO file is a disk image. It should NOT be burned as a regular file. You need a program like BurnAware Free or ImgBurn that can burn an .ISO image. I think a CD is best as there is no way anything can write on it after it is made, but the USB may be more convenient and easier.


2. Now, please boot off of the newly created GParted CD. See How to Set BIOS to Boot from CDROM for information on how to boot from the CD.

You should arrive to the following screen:

Press the ENTER key

Posted Image
By default, "do not touch keymap" is highlighted. Leave this setting alone and press the ENTER key.

Posted Image
Next, choose your language and press the ENTER key. English is the default setting [33]

Posted Image
Once again, at this prompt, press the ENTER key.

You will now be taken to the main GUI screen below

Please take a picture of this screen (camera or phone pictures will work just fine), and post it here for me to see. It is very important that you complete this step.

Quick silly question:

I have a ton of DVD-Rs but no CD-R's. Will ImgBurn burn the image on a DVD-R and can it boot from one or does it absolutely have to be on a CD-R?

I don't see why it shouldn't work. Give it a try and let me know if it doesn't work.

Go back to that screen. Highlight the /dev/sda1 partition and click Resize/Move at the top. Then, in the dialog/interactive box that appears, resize the partition by dragging its right edge to fully cover the unallocated space so that there's 0 free space after it. Click the Resize button then click Apply when prompted.

Let it do its thing, and when done, restart your computer and let me know if it now boots into Windows.

Ok, just to make sure I did this correctly, there was 0 MiB of Free Space Proceeding. I moved the partition and now there is 10 MiB Free Space Proceeding and 0 MiB of Free Space following.

Is that correct?

You mean there's now 10 MB free space before the concerned partition?

You should only drag the right side and not touch the left side. Did you already click the Apply option by any chance?

Hi, Skiminims. I'm heading off to sleep now. If you're still struggling to do it as instructed, then just click Cancel and shut down the computer for now. The important thing is that you don't click Apply without doing it all properly. I'll give you my next set of instructions soon.

I have not yet applied any changes. I will cancel and show you what it says before I move the partition.

Ok, no problem. We'll worry about that one later (if necessary). I'm thinking of something else now. What Windows version do you have?

If it's Vista/7, are you able to access the Recovery Environment?

Normally, it's done by repeatedly tapping F8 right before the Windows loading screen. And when you do, there's normally an option called Repair your computer right above the Safe Mode options. Do you have such an option?

    • Download OTLPEStd.exe from the following link and save it to your Desktop: mirror1.
    • Finally, if you do not have a file archiver like 7-zip or Winrar installed, please download 7-zip from the following link and install it: the mirror
  • Once you have 7-zip install, decompress OTLPEStd.exe by rightclicking on the folder and choosing the options shown in the picture below. Please use a dedicated folder, for example OTLPE, on your Desktop

    Posted Image
  • Open the folder OTLPEStd which will be created in the same location as OTLPEStd.exe and right-click OTLPE_New_Std.iso. Select 7-Zip and from the submenu select Extract files... and extract the content onto your Desktop in a OTLPE folder:
