Something to do with computers

I don't know what's wrong with our desktop computer, but despite it's cable internet connection, it is sooo slow! I'm not sure if it's something to do with the computer memory or RAM or what, but it annoys me! I'm so glad I have this laptop, it is much faster. Actually I don't know the last time we ran a virus scan on the desktop, maybe that's the problem. I guess I could try that out and see if that helps.
