I got a fire stick yesterday and was trying to connect it to my non-smart Vizio TV. I couldnt get it to work, so I googled "Amazon Fire Stick Support number." Stupid me called the first number that popped up, and I reached a very nice, polite man who asked to remote access my computer to see what the problem was with the fire stick (this just goes to show you how technologically inept I am- obviously he couldn't connect to the fire stick through my computer. Hindsight!). He showed me that I had a Trojan horse and wanted to connect me to another company that could fix it. I said no and hung up, but not after spending 40 or so minutes on the phone and letting him access my tablet. I am wondering what to do now. I have Windows 10 on a Surface Pro and have run a full scan with Windows Defender (nothing showed up) after turning off the wifi and powering down and then back on. What other steps should I take? I am terrified to use any of my devices now!
I apologize if I didn't follow protocol exactly. Please advise if I need to give more information.
