If you have a high speed Internet connection you need a firewall program. A firewall program keeps those who want to hijack your computer from gaining access to your system. You really do not want someone else running your computer.
I suggest you purchase and run Norton's personal firewall program. Your firewall should boot up with your computer to protect it from invasion. A free personal firewall program is available from Tiny Software.
firewall program是 防火墙程序 的意思,Norton 是诺顿的意思...其他的我就不是很明白了...希望有懂的帮忙翻译翻译.~!
