My wife was in another room and looking to watch a TV show and hit a link to download - similar to others a screen popped up and said the computer had been infected and to call Microsoft on the number provided which she did. She had been on the phone a few minutes when she came in to tell me - she had given him access to the computer via remote access - he kept her busy by drawing pictures on the screen whilst he was quickly turning of the virus software.
I just turned off the computer with the hard switch and she shrieked as I did because he had said whatever you do don't turn off your computer. He stayed on the phone another minute trying to get her to turn it back on as I said repeatedly it was a con.... she never believes me.
I gave her my iPad and said to google the number... she now believes me. I turned the wifi off, and tuned it on again - can't get the antivirus to run so will take to a local doctor. Changing all passwords for good measure.
BEWARE - the site is very convincing, they are persuasive, but dangerous. I hope we stopped them in time, but fear they may have scraped off some personal information. No money changed hands fortunately.....
