Dell dell windows xp desktop computer Review

I hate my dell window's xp computor it is a large bust to me I did use to love it all- though now  I do hate it. It has become real slow to move from page to page and I have to wait a very long long time for the page  to  come clear once I have clicked on the site or page that I want. I feel that there are virus in the system and no anti- virus softwere was allowed with this system or If so I must have missed it . I am not that pc savy as it is so I need something that is dummy friendly. Like systems for dummies that would  be me. I was told that this was the best sort of machine  but you could not prove it by me. I would though recommend this machine for beginners . It is a good system to learn on and to get you started in the world of internet. I am not sure if this is what you were looking for in a review but I have just had so much mistrust in this system.   Thank you for your time
