Caller Type: Unknown
Phone Number Report: Using some sort of predictive dial software... hence the long pause before the person begins talking (usually a sure sign of a telemarketer, or a scam).
Identified themselves as some sort of global network thing, claiming that there was a problem with my microsoft computer.
I'd heard of this scam before, so when I told him I didn't have a microsoft computer and they had their information wrong.
Asked me 'how can that be' since they could see I had a microsoft computer. Told him I had an Apple computer... and he hung up.
