What does the man want to know?

W: Would you mind taking a look at my laptop when you get a chance?
M: I have a lot of work to do today.  I can look at it tomorrow morning. What is the problem?
W: I can only have two programs open at one time. Then, if I open up a third, it freezes and I have to restart it. It’ s really hard to get work done when it freezes up that much.
M: Okay. I think it’ s a virus. I’ II come to your office and check it at 9: 30 tomorrow. Before then, I want you to back up all of your important files.
