warning is untrue and very annoying!?

Windows is sending a message 4-5 times or more daily,
that i have various spyware in my registry. this warning takes up my whole monitor so i have to go through a series of questions to delete the warning before i can continue.
Also, i do have spyware protection, and i am not interested. i dont think this falls under the criteria for a pop up.
it dosent seem to be a typical pop up. it says it is a warning
from windows,and shows the windows installation wizard when asking if i would like to download various anti spyware software
i want to find out how i can delete this warning/offer. it is very frustrating, and annoying! this warning is random and seems to pick the worst times to "pop up". so how do i delete this, and prevent it from re-ocurring? i do not recieve any other pop up advertisments. i have a great antispyware in my security suite
already, and it finds nothing such.can anyone help? warning
shows a different infection every other time,
which tells me it is not true? can anyone help? chris
