Well, I've just had a second call in as many weeks from the scammers trying to hijack my computer.

By the way, the caller ID shows no telephone number. Obviously.

The first time:

Hello, is that Mr Landau?
- Yes.
I am calling from [somecompany] about your computer.
- What does your company have to do with my computer?
Well, we have discovered that your computer is infected with a virus.
- @$%! off. (I hang up)
In hindsight, I realised that I could have wasted his time, delaying him for at least a few minutes from messing up someone else's computer.


The second time:

A few minutes ago I got another call. This time, I pretended to be curious. Here is an abbreviated version of the conversation.

Press the Start button. Do you see My Documents?
- No.
Press Start. Do you see the Run command?
- No.
What do you see?
- Accessories; Games; Graphics; Internet; Office; Other; PlayOnLinux (that should have given him a clue); Programming; Sound & Video; System Tools; Wine.
Do you have the Windows flag button?
- Yes, I do.
Please shut down all your windows.
- OK, hold on, let me save what I'm doing... Right, I've closed all my windows.

Press the Windows flag button and R at the same time.
- OK.
Do you get a small window or a large one?
- Nothing happened.
Do you have Windows 7?
- No.
Do you have Windows XP?
- No, I don't believe I do.
Is it a laptop or desktop?
- Laptop.
How old is the computer?
- Um, I got it in 2008. Three years old.
(Pause... he hangs up!)

My question is, what could a person do in preparation for the next call, to waste as much time as possible of these deceitful scammers? The more time we waste, the less time they have to mess with a more gullible person.

I did think of using Windows in a Virtual Box, but I don't have Windows. Although, if I did, it would run very slow on my computer, making it excitingly time-wasting!
