how can i block the page wickedseeker?

Answer 1

You could add your loopback IP address in your host file (C:\Windows\System32\drivers\etc\hosts) and tell it that 127.0.0.1 is the IP for wickedseeker. Any attempts from your browser to hit that hostname will resolve to your local system. That wouldn't necessarily resolve the issue of a site embedding content from another site (say through IFRAME tags).
