I noticed traffic dry up on my website and my site no longer ranking for any of the things it used to be #1 for on google. I logged into Google webmaster tools and noticed that "what googlebot sees" was all spam words like Viagra and Livitra. I looked at the google cached versions of my page and noticed a hidden div at the bottom of the cached page.
It appears my website was hacked similar to what this article describes

But I can't understand anything on that page, half is in broken english and the other half is in geek! What do I need to do to fix this?? And how do these guys even get files onto my web server?? Someone please help!
