My dad's friend gave me a computer that was only 6 months old. I have been using it for a couple of years now. It has windows xp pro, but today I got a virus, I was able to get rid of the virus, but I had to restart my computer. When it finished restarting and I tried to log in, it automatically log out by itself. I thought it was a virus that might still be on my computer, but it is unlikely. I scanned with 3 different anti virus and malware programs and they got rid of it for sure. After some research on the internet, I figure that the virus messed up my Windows. Since I got the computer from someone else, I didn't have the original Windows CD, but the guy made me a copy. So I used the copy and now I have to put in the Certificate of Authenticity which I don't have. Sinse i already set up the Windows, it doesn't log out by itself anymore, so I know that was the problem, but now I have another one. How do I get the Certificate of Authenticity? My dad's friend moved and I can not get the original CD from him. Is there another way to get the Certificate of Authenticity or should I go out and buy a new XP CD. Or should I just get Vista?
If I update the windows, will all my files on computer go away?

I can not use the internet on that computer right, now I am on my phone, so don't suggest any downloads. Thank you.

Oh, I can even do anything on that computer right now except try to log on and it says I have to put in the Certificate of Authenticity.
