Ebay spyware

[bodgit]

How much spyware have ebay got. This morning I was looking at battery chargers from argos and halfords. Just now as I logged onto ebay the very same chargers are in my suggestions page. I was also recently looking at buy a gift,s website and ebay keep suggesting things from them.
I think it stinks they areable to spy on me and would like to know if I can get rid of the spyware from my laptop.
