I used my Team Speak most of the day Sunday with no problems at all. Monday evening I try and get on with some friends and I can hear them but the can not hear me, I check connections and everything is ok. No changes had been made to the PC, no updates. I run Bit Defender with fire wall on. About 8 pm I get a phone call from some guy with a foreign accent saying he is from Windows and he knows I have a virus on my PC and he can fix it. I asked how he got my phone number and he said through windows on my PC! I hung up on the guy thinking it was a bunch of crap. Tuesday after work I uninstall TS and re-install. Now it will not work at all. After working with it for about 10 minutes the guy calls again saying the same thing. I told him to FO and hung up but now I am starting to wonder if something is up with TS and this guy calling. I am going to start TS again tonight after work and see if he calls I know the headset works I tested it in iRacing and I can hear and talk to people fine. I have a friend that something like this happened to a few years ago. He had to pay the guy and the problems with his PC went away. Anyone else ever have this happen????
