This was an Indian who claimed to be calling to help to protect our computers that run Microsoft programs. We are an Apple family. We told him to get a job where he can earn his living honestly instead of scamming people.
Called me and said they were from Windows Tech Support. They tried to tell me that I had many errors being reported to Windows and they would scan my computer to try to locate them, before the errors caused a fatal computer crash. He gave me a number to call to verify who they were, 281-882-3486. This is a scam so beware.
