My friends mother has a Windows Trojan on her laptop.
My friend has started it in safe mode, but is still getting the pop ups, even in safe mode and it will not run Malwarebytes or superantispyware.
What is the best malware remover that can be run from a CD or USB key, (before the OS is loaded), as I cannot see another way for him to remove this infection.

You could always rename Malwarebytes exe file to something else

right clicking on it and select rename.

it should run then

Problem solved, I booted the laptop from an Avira rescue disk and cleaned it up that way.
It found 5 trojans and 2 viruses .
After I checked what was running at start up and found there were 15 items running, there are now 2.
Before this surgery it used to take up to 10 minutes to boot to a working desktop, now it takes 2 minutes.

It is running Vista with only 1GB of memory installed, so I have advised them to fit another 2 GB's, and it should fly then.
Although this laptop will take 4GB's of memory, it has a 32 bit OS, so it is pointless to install 4GB's.

Nice one - all you have to to do is ensure the thing has some sort of AV on it in future!

For future reference there is a major tool which can be downloaded from http://oldtimer.geekstogo.com/OTL.exe. - burn to a CD and this will give you a bootable tool that will fix all sorts of things.
I have used it once or twice and don't think I have scratched the surface of what it can do yet!
