Unable to open www.tamilwire.com, need help.

Dear Team, Last week I had accessed www.tamilwire.com & www.divxturka.net for downloading movies. I think the site has breached my browser security settings. Since yesterday i'm unable to open that site from firefox & Internet Explorer. Rest all other sites are opening properly. Thanks... == URL of affected sites == http://www.tamilwire.com, http://www.divxturka.net
