Desire help needed

I will say first of all this is my first ever post mad eon this forum. I got my desire earlier today and cant help but notice there is a lot of rubbish installed on it that i will never want or need. My only problem with this is i cant seem to be able to get rid of them, There is an app i believe for getting rid of these but it only gives me a datacode as the link to get the app and i cant for the life of me work out how to read a datacode on the phone.
PLEASE HELP ME.

Hi Frazer,

When you say "data code" do you mean like a QR barcode? If so download this app for your phone, http://www.androidpit.com/en/android/market/apps/app/com.google.zxing.client.android/Barcode-Scanner
Search the market for barcode scanner.
