Good job doodle. I just know that something was 100% at sexbot file, because it always wrote to registers when I ran the game. Plus I didn't donwload anything else since I downloaded sexbot and I am not visiting some shady or wierd websites. I don't know why or what was doing that or if I was just unlucky. And since I deleted sexbot file and not playing it, everything is fine at my PC.
But also this isn't classic virus. It's adware and it activates only when you run game itself. So your antiviruses won't catch it. Try to run the game and then check registers if something appeared at place I mentioned earlier. My antivirus also didn't detect anything and same adwcleaner when I run those before checking registers. Maybe I am being paranoid, but I know what was happening at my PC and when it stoped and everyting leads to sexbot from pixeldrain
