Just had a phone call from an Indian man, he called from this number 15167469209 he said he was from Windows and he told me that I had a lot of malicious viruses on my computer, I then asked where he was calling from and he said Manchester then he went on to tell me to press the Windows key at the same time as the letter R and it took me to an event box, his next request was to type in that box ammy and click something else that I've forgot now and it took me to a green screen that belonged to a company named Ammy, on that screen was a tiny box that said 'read this before giving any information to anyone you don't know' I then clicked on that and it told me that a scam is going around from India saying they are from Windows please freeze your bank a/c etc. etc., at that moment the line got lost so I called BT and told them the story and they have known about it, so they checked my computer and told me because the line cut off and lost contact my computer is safe. It's the first time in my life that I have experienced anything criminal!
