Called and did not leave a message

Someone from 205-863-9588 with ID name of J.Ramos called.  Did not answer phone and they hung up leaving no message on answering machine.

I answered the phone, there was a delay before the guy responded.  He said he was with United States America Maintenance and that my computer was infected.  He asked me if I was in front of my computer.  I told him it was none of his business.  He said it was important that he show me all the files that were infecting my computer.  I asked him to remove my number from his call list and he said he was there to protect me with America Maintenance.  He argued with me and would not hang up.  I hung up on him.

Called by this number at 6:45 AM . Did not give the caller a chance to barely speak and told them(in no uncertain terms) to never call me again.

Received a call from J Ramos 205-863-9588.  She said she was from microsoft and that my computer had many infections.  She asked to get on my computer so she could show them to me.  I hung up and called the number back, its not real.  Definitely a scam!!  It is an odd feeling to actually talk to a person who is trying to steal from you.
