Need Help!

I seem to have a problem and im not shure if due to the spyware.
I've ran numerous virus scans with Norton and Mircosoft Spyware, and the program hasnt still found anything. I also have a white dull wallpaper, i've also tried to change it many times, but it still hasnt change one bit and its still white. And when i open up my Inernet Expoler it comes up with this message.

It also tells me to buy there program which is "Spyaxe and Spytrooper" and i've download it once, but uninstalled it, because it tells me to pay for it. Pleaseee Help
by the way i have a DELL Dimension 8400, and all my programs are all up to date.

THANKS IN ADVANCE!

 

Oh yeah it also gives me a yellow exclemation warning sign that tells me to download spytrooper, on my taskbar

 

After doing most of the process, the programs still hasnt fully deleted the program, basically everytime it finds it, i earse it. But then when i restart the computer and after awhile i get the noitce sayiing "Your Computer Is Infected " and it tells me to download Spyaxe, but then i dont touch it, and it automaticaly downloads spyaxe by itsself.
Could there be another way to find out these problems?
THANKS! for reading

 

So far i've got rid of that problem
