Similar events. Screen locked up and was prompted to call the 888 number.
Turning the computer on/off was still locked. They charged me 400 to rid my unit of viruses and another 250 for 3 year warranty. Four days later locked up again. Called microsoft tech directly.
They got in and said nothing had been done. Disputed charges with bank and "merchant" agreed for full refund. Now I have to reinstall windows 8 to get rid of all their stuff they downloaded. Some of the software they put on there you can not even delete.
Others even after deleting are still running in the background.
Very crafty scammers. At least I got my 650 back.
