What kind of idiot...
I used to wonder what kind of idiot gets caught out by this sort of thing. Then I had a call from my sister about one such email (think it was a WhatApp nasty).
"Why did you click on the link, you don't use that?!"
"But it was from a friend!"
"Yes, but you DON'T USE THAT PROGRAM!!!"
Now I know what kind of idiot...
