Please beware of these. My daughter who has a slight disability got a message to update some of her software, she, thinking she was doing the correct thing clicked on it. Long story short it locked her computer up tight, she got a message her computer was being held ransom for 1 bit coin to release it. Value of a bit coin, approx. $250.00. They got fooled, her computer is old so we just disconnected in from the internet. Thank God she had not done any sort of banking online.
