Ive started receiving some popup by a site called Gamiss, only when I visit ebay. Sometime ago, I was receiving 'Youve Won' popups too; I thought they'd cleared but now this latest. Always and only whilst on ebay. Very annoying!

Besides installing the adblocker, why is there no real solution to stopping this by ebay?

Or is it more about revenue generated ads as opposed to the safety of buyers and sellers that use ebay?

I use latest software to keep my pc clean; antivrus up to date and firewall etc.
