I picked up on the 4th ring and heard an automated voice say "good bye".  A robo call of some type.

Called - asked for Jeff -  I said this is a business no jeffs here they said uhhh huh and hung up

Caller said I must turn on computer immediately because it was being hacked. Yelling tone of voice. Heavy foreign accent. Said company name was Cyber securities and he was a Microsoft security specialist.

I just received the same exact call today and said someone was trying to hack into my computer and I should turn my computer on. I told them I wasn't turning it on and hung up on them. If it was a call from Microsoft I'm sure caller ID would have said Microsoft.

I got the same call telling me my computer was being hacked. I could barely understand the guy.  I hung up on hin and he had the nerve to call right back and ask me why I hung up on him.  I told him I knew it was a scam and that I had already heard about it.  Then I hung up again.  I haven't had them call back this time. lol Just mention "scam". That usually works.
