Hi all, I just registered on this website because I have got a trojan horse & rootkit problem on my HP laptop which currently runs xp. I cannot get rid of that problem and a reinstallation of an OS is required.
As I always wanted to rather use Linux and had already checked out Ubuntu I thought I could just download Ubuntu on a usb stick, plug the usb stick in and it would install itself.
However, through trailing through a lot of installation guides I am very confused now. I do not know very much about computers and all that special lingo.
Is there an easy way to install Ubuntu from a usb that gets rid of everything which is on the laptop for absolute beginners?

Any help will greatly be appreciated.
Thanks! Annette
