spyware quake removal

[monolisp]

Hello,

Does anyone know how to remove spyware quake from the system? I downloaded the latest updates and removed everything and immunized, but there is still an icon in the system tray that pops up and says

"
Your computer is infected!

Critical System Error!
System detected virus
activities. They may cause
critical system failure. Please,
use intimalware software to
clean and protect your system
from parasite programs.

"

Then when you click on it it takes you to: hxxp://www.spywarequake.com/?aff=240

It asks you to buy this program.

Any help in ridding my system of this pest would be very much appreciated!

Thanks,
J
