This is just gold. I highly suggest that this video is mandatory watching for all my clients, friends, parents, relatives, anyone that uses a computer. These type of scammers have been calling people here in Australia now for quite a few years, but only recently have they spread to other regions of the globe.
It all starts with a phone call you get on your home phone. The caller indicates that they are from “Technical Support” or some similar company and they tell you that there’s some problem with your computer and that they are there to help you resolve it. The scam then involves them walking you to a website to install some very valid remote control software after which they then proceed to show you all the “problems” with your computer and request money from you to “fix” them.
Be warned – NO ONE WILL EVER CALL YOU TO HELP YOU WITH YOUR COMPUTER….unless of course you have a prearranged and PAID relationship with them – i.e. – your IT support company or your son (yes Mum, I’m talking to you here)
