"Scam alert. Are you getting phone calls by people claiming to be tech support?"

It's only one of many. Where the cold caller "says" they're from, or what problems they "presumably" report, may vary. (See Tech Support Scams - Help & Resource Page also one of many posts reported on the subject)

We can only hope folks aren't taken in by these scams...
