These people are posting to youtube videos and many other places pretending to be customer care for genuine companies like AVG, HP, Quicken, Dell, Skype etc.
Needless to say – they are NOT the official support and are likely to incorrectly claim your computer has viruses and needs to be fixed for $150+ etc. Be very wary of any claims that people on the end of this phone number make.
One day I will call, test and record what happens.
They post the US based phone number “1-855-676-2448”
