Spyware Guard 2008

I am working on a PC that has Spyware Guard 2008 on it, and for some reason, I am unable to install Hijackthis or Malwarebytes Antimalware. I even tried using a flash drive with the programs on it, to no avail! I have read the manual uninstall instructions posted at bleepingcomputer.com, deleted all the files it indicated, deleted the registry keys indicated, but when I reboot, there it is, sticking it's tongue out at me, laughing while it performs it's dog and pony show. Is there anyone with advice that can walk me through how to get rid of this nonsense once and for all? ***Edit Hijackthis Log posted

You will need to download Hijack This and post in the HijackThis™ Logs and Infections Removal Forum. Here is how to do that, read it carefully!

If you cannot run HijackThis or other tools, just skip the step you cannot do and create a new topic without HijackThis log. Somebody of the anti-malware team will be able to help you.

Do not reply to your own topic as helpers look for topics with zero replies and if you are not being helped after five days, I recommend that you read and work through this to get high priority:

Good luck!
