Sister got a pop-up about her computer being locked and was told to call the following number: +1-855-207-8763
The guy tried to syskey her before I could call her and have her force the shutdown on the machine.
While he was on her machine he started messaging through Facebook (from her account) antagonizing me since I support her tech (lol)
Anyone looking to troll a scammer please give them a call! That number was active as of 2:19 EST 1/10/19
Also can post screenshots of the convo if anyone is interested!
