855-873-6729

I received a message on my computer saying it was a Zeus virus and to call Microsoft at 855-873-6729.  I talked to the person over 45 mins. as we were trying things to fix the computer then he took me to a website supremo.com and he was fixing things in the computer and had control of it then the line went  dead on the phone.  Was it Microssoft or someone hacking my computer my? When we called back the number the same person answered and wanted to know who we were talking too and we kept saying him.  We hung up and he called back from a different number 561-757-4186 out of Florida but I was talking to him in Nevada. Does anyone know anything about this?
