We had a short holiday in France staying with friends. When we returned home I found my Visa Card Blocked & it was used twice without my knowledge. I never used my Visa Card while in France & never out of my sight. I did have my Laptop with me but not connected to the Internet. There was a Dongle on my Laptop, once when I used my Laptop to download photos I had taken there was a blue screen & my laptop closed down.
