Living in the suburbs of Paris, today on the 20th of Fev. I received in the morning at 9 42 a call from this number. She just asked me if was speaking english, I said yes, but as she said she was Marina with a russian-sounding name, I asked her twice whether she was speaking russian, because I'm bilingual translator, then she hung up.
Scammers calling saying windows 7 support, they do not even know anything technical. Just hang up, block contact and move on... Scams like these are ancient and only work if people are stupid enough to fall for them.
