Anti-virus software are programs that run on your computer. At any one time there are lots of programs running on your computer. The more that are running, the slower the computer can work. So when you install a new program like anti-virus software, it is an extra program to run which will make your computer slower. It is still important that you do use anti-virus software, even if it does slow down your computer.
