Locked up my PC and to call this number with MS logo. I called and they got on my PC disabled my Malwarebytes and downloaded a Trojan on my PC AMMYY and a ccleaner. Wanted 184.00 I cancelled my card. Turned my Malwarebytes back on and it detected the Trojan right away and quarantined the short cut I clicked on.. I then ran a scan and it found the Trojan AMMYY and removed it from my hard drive.
