Cant Do The XP Cleaning Procedure

I am trying to fix a friends pc thats in a bad way,
its constantly sending data out over Ethernet and
the icons in the control panel don't do anything when you
double click them,

I have done all the steps in "read and run me first"
I am now trying to install super anti spy-ware but when
I double click the installer nothing happens, I am guessing
this is related to problem with the control panel icons

I have tried to also install in safe mode but still the same
problem

Any help would be great :cry
