Hi Robert, Dad is helping me with our computers. One computer is a farmerinthedell with XP and a 500 GB hard drive. We are unable to update the security suite. We need to update to a 1TB or greater, copy the data and install Windows 7. What is the easiest way for us to do this? Our other computer is running out of hard drive space and I'm not sure if I have the best security suite installed - I have a free version of Comodo. Will you call?
