What is your favorite security provider or which one work best with flight sim? I have Norton, and have not had any problems with this and FS9. But two days ago, searching with google, I was being redirected to strange websites. Scanned with Norton and it did not find any problems. After searching the net, I used Hitman Pro, and it found a trojan, blasted it, and google is back to normal. A little disipointed that Norton missed this.
