If you are still using a computer that's running Windows XP, it's probably time to upgrade. XP is a 10 year-old operating system, and the world of computers was very different back then. Now that we are all always connected to the Internet, security requirements have changed a lot. And Windows XP hasn't kept up.
Apart from being vulnerable itself, XP does not run the latest verstions of browsers, so that further compromises a system.
A new computer, which runs Windows 7 and the latest versions of Internet Explorer and Firefox, probably costs a lot less than you think. This is due to hardware development outpacing software demands, leading to a situation where even the most basic hardware can run the latest software.
Additionally, Windows 7 comes with a lot of features that make it easier and faster to use.
