Who called from 8583453171

Received a call from a man with a heavy accent, said his name was Chistopher Woran, claiming to be from Microsoft.  I asked him how I knew he was from Microsoft as the number he called from came up as unknown.  He said I'll provide you with a number when we're done.  He said they were getting signals my computer had been infected with a virus.  I told him I was busy & asked for the call back number.  This is the number he gave me.  What agency should this be reported to?  Beware!

I just got the same call and he gave me the same number.  Said his name was John.  Does anyone know what's going on?

My elderly mom got scammed by this guy yesterday. Look out - it is a phishing scam! Do not give them any info, do not give them access to your computer. The guy has nothing to do with Microsoft.

Have had these calls before. Keep him on the line so he does not get to call anyone. Why can't the phone company be held acountable for a this scam.
