Who called from 5875453345

First call from this number.
The phone was next to me so I answered immediately.
No one there, then disconnect.

I couldn't understand the company name but he was telling me my computer isn't safe. I hung up.

Caller I.D. showed "Unknown caller"; I let the answering machine take the call and caller then hung up.
