I am sure that by now most people are aware of this problem, so I'm just putting it out there as a sort of gentle reminder to be vigilant.
You all know the drill... you get someone (usually located in India or the Philipines), saying their from Microsoft etc etc, you've got a problem with your computer blah blah blah.
The idea is they take control of your PC remotely and usually end up messing it up, then have the cheek to suggest you pay them to 'fix it'.
Just be alert. NEVER give ANY banking details out.
I won't harp on about it, I'm just putting out the reminder, because I've had one or two of these calls myself very recently. They never seem to learn.
Thanks.
