Hello Sirs,

I have a little problem with my pc and i dont know if this a fault from my Norton Antivirus 2010 or not.

I tell you little fast my story,i have a modem router in my house and i have connect 3 pcs.until last week i could see a web site with games (www.offgamers.com) but now i am seeing only the first page and not the section of it.

When i am attempting to hit the section buttom,the page freeze.This is happening also with my 3 pc.

This is only happen with this url.I have contacted with the admins of the site and they told me to put some "hosts files" on my pc but nothing happened again.
