It started this morning when I attempted to get on Internet Explorer.
It told me to finish my registration for cloud. Then it said WARNING!!
You have been hacked and it gave me a phone number to get it fixed. They said it was a Microsoft number. They wanted money.
I have Windows 10. I can get in to most of my web sites but the warning keeps popping up, telling me that my computer will be damaged if I don"t pay Microsoft to get it fixed. I think it"s a scam????
