Google Webmaster Tools lists the most frequently used keywords on your site. This is great, but for some reason my webhost username is being seen as one of the top keywords. What is causing this and how do I fix it?

Because I'm using Joomla, I have robots.txt set to disallow most of my folders since the site is stored in the database. But I'm still missing something because my username shouldn't be showing up at all as a keyword. I haven't used it on the site or anything like that.

A 2nd question; my footer contains my copyright with link, and a link to the site's privacy policy. Because the footer is on every page, Google seems to put too much importance on the keywords and links in it. I can use nofollow on the links, but how do I stop Google from thinking "copyright" and other words in the footer are the most used keywords on the site?
