Problems with XTube and Pornotube

[alex]

Can someone help!!!! Recently I tried to log to Xtube, Tube8 and
Pornotube but I get redirected to another site (http://216.255.178.179/
webcams/, or to a fake Norton Antivirus site). I have Norton 360
installed on my computer and when I run it, it detects nothing, no
virus or spywear. I tride to use Mozilla Firefox and explorer and
there is no difference. When I log in to Youtube, XHamsters it works
fine.

Any one know what is happening???

Thanks, Alex
