I received a call from 480-259-7290 and it was a heavy accented male that sounded like he was from India.  He said my windows computer was infected with a virus and wanted to try to "help" me asking me to go to my computer.  When I asked him how he knew to call my phone number when I built my computer myself, therefore my phone number wouldn't be associated with a phone number, he hung up.   He said he was from Research... so be advised if you get any cold call tech service, its likely a scam.
