This caller phones up about computer error reports from my computer. I will not give out any info. The callers have been both male and female with english that is difficult to understand.

6/8/15

I received 2 calls I didn't answer no voicemail left

Just received the same call for same reason. I told him that I think he is a scam and not to call back.

I just received a call from this number.  Was told they had been receiving an error message too.  No info given.  Scam??

4 calls on my machine when I got home but never a message.  I am blocking them.  From previous reporters, sounds like ransomware hackers.
