Security Risk After Todays Patch?

Hey guys, I was wondering if anyone is having this issue as well? A minute ago i launched WoW and it started to patch but after 5 secs my Norton Security (have used them for years with no problems) stopped the download because it said there was some risks. The error Norton gave me was, "Wow-4.0.1.2210-enus-tools-downloader.exe detected by Sonar." It then it recommended me to restart my PC, so I did. Launched the game again, and got the same result. I played last night for a decent amount and i was not getting any issues like this. Anyone know why this is happening? Anyone else experiencing this with Norton or any other Virus software you have on your machines?
