How was i born?

Little boy:
Dad, how was I born?
Dad: Well son,
your mom and I got together at Yahoo.
We 'setup' a date via 'e-mail'
and
met in a 'cyber cafe'.
Your mom agreed to 'download data' from my 'hard drive' through 'data cable'.
Just when I was about to 'transfer', we realised that none of us had 'installed' a 'firewall'.
It was too late to hit 'delete'.
Nine months later a 'pop-up window' appeared,
saying
Congrats
'you have got a 'Virus':-
