Computer has what?

My computer is running slow and I have this program to clean the computer, so I called them to see what I am suppose to do.  They took over the computer like a pirate takes over a ship.  I watched in amazement as they diagnosed my problem.  The tech came out with a word for it.  My words were, "My computer has what?"  What is it?  It's a germ.  Okay if it were human I would give antibiotics, so what do I do now?  So they proceed to tell me what to do, yea right.  Finally they said they will take care of it, just don't touch it until you are told to do so.  It will take a few hours!  No, I won't survive.  I will get busy elsewhere.  I would walk by it not touching and it was finally ready.  Wow, is it fast again.  They took all the germies away and didn't even use an antibiotic!.....
