My dad found this number by googling for a support number for Magic Jack. They had him install GoToAssist and showed him “proof” he had been hacked by Mexicans over the last year. They syskey’d him and wanted $250 to fix everything. Luckily he didn’t give them any money and I was able to clean up his machine.
A quick google of that number shows it’s been associated as tech support for Spectrum, Dell, Yahoo, MagicJack, Silver Singles and Garmin.
