Who called from 6162982588

Incoming call from Holland Michigan.  Did not leave a message. I blocked the number.

Hadji with Indian accent called and told me he was going to fix my computer.  What can be done to stop this?

Didn't answer. They should not have my cell number!!!

Got a call a few minutes ago from 'Windows Computer Technical Support' advising me that my 'Windows Computer' is reporting errors. I told him that this was the first time in my 40 years as a computer tech that a powered-down computer was producing errors.
And then the phone went dead..

call from "microsoft" tried to instruct me to press the windows key and R at the same time.... I did not and ended the call.  The call was very sketchy.  Normally would not continue the conversation, but we have been having virus issues with our computer to begin with.
