Pop Up thingys and why?

[DisasterEggs]

I seem to be plagued with pop ups that pop up behind what ever page i'm doing something on. They also seem to be related to what ever i'm reading about.
when i'm here they are usually for prams or vibrators.
I have Norton firewall thingy so why do they keep popping?

have you downloaded any free stuff e.g. a desktop clock? usually these pop unders are the catch...

nope.

no clue how you got it then but would suggest deleting all of the cookies on your computer.

Do you use adaware? and spybot?

They are free, and really worth getting.

Which browser do you use? Firefox is the best.
