telephone hackers - can we upload something?

I had one of these calls yesterday - "your computer has stopped
communicating with the Windows server", or something like that.

I used my usual: "hang on while I get the police on the other line";
that usually makes them hang up pretty smartish.

However, thinking about it afterwards, I wondered: would it be possible
to devise something that could do something to their systems, while
pretending to do whatever they ask? I've never gone beyond the initial
call - I have always seen through them so far, it's not been difficult!
- so I don't know what they ask you to _do_.

I suspect it isn't likely to be possible, but it would be _so_
satisfying ... (-:
