I got a call from this number.  They said I had a really bad virus-which I do the Trojan.Kotfer!gm2 which I got after buying some downloading software from a seller on Ebay who afterwards went off line.  This is a horrible virus that keeps having to get quarantined by Norton every hour in which I have to restart.  They said they were Windows tech support to fix the virus.  Obviously they are the ones who gave me the virus.  So they have access to my info obviously.
