AdBlock Plus Or Built-In Adblocker For Internet Explorer?

Hello,

I’m running windows 7 premium & just installed the new „AdBlock Plus“ for Internet Explorer. I’m also using the built-in IE adblocker . Is one preferable over the other? Will having both pose a problem?

Please help.

I did not find the right solution from the internet.
