I am an 83 year old silver surfer with a some knowledge of the inside of acomputer having built three in the past , recently I have been pestered with phone calls from a call centre (you can hear lots of converations in the background) and the man says that Microsoft are recieving messages from my computerand that he can fix the problem If I were to switch on my computer and give him a few minutes of my time , I said are you calling from Microsoft itself ? he said yes so I said which of my machines is giving the problem he then said the oldest one , to which I replied It has not been switch on for over a month as i have been away.he thensaid that that didnot matter s they would get the messages from my computer even if the machine was not switched on, unless I am a complete idiot how could my machine send messages to microsoft when it is not connected to WWW.This sounds like a scam to me.and does Microsoft cold call in this country.
