What is the conversation mainly about?

W: My computer has a problem. It doesn’t scroll down any faster whenever I am using a word processor.
M: Well, then have you checked for any viruses recently? Sometimes, if you don’t have it periodically checked and let the viruses build up, the computer slows down or doesn’t reboot.
W: Wow! How do you know all those things? I wish I could do a lot more with my computer and do it faster.
M: Then why don’t you visit the computer center? They will teach you how to deal with any basic problems you might suffer from malfunctioning computers.
