scamming

i got a phone call this morning from someone claiming to be from microsoft trying to tell me there was something wrong with my computer and he needed to fix it and would walk me through the steps over the phone. sounded completely ridiculous to me cuz i'm pretty sure no where have we listed our home phone number with any sort of registration of our computer. i was pretty sure it was a scam when he said something like "...and it will shut down your whole computer. you don't want that, do you?" he started to tell me to press some buttons to help fix the problem but i just hung up on him. after doing a bit of a google search, turns out it was a scam. here's an article from the age a couple months ago. if i did think there was something wrong on our computer i would be either getting a friend in IT to help or taking it to a computer repair place, not taking advice from someone who called me. i guess there are people who would just assume it's legitimate though.
