Installed plugin "Shopp" now /shop redirects to external site

I installed the plugin Shopp recently, and the virtual link it created to list all the products setup redirect to the website nextdaypc.com. So I deleted the plugin and made sure all of the files were removed, and I also started looking at the database to see if there was an entry that would cause this, but couldn’t find anything.

Does anyone know where I can look to fix this redirection?
