Ive never experienced this problem before and I dont know if or what I did, but every time I open up the BC Launcher, it attempts to re-download bout.dat and then Symantec comes up and tells me its a trojan. I dont know why I need to re-download if there was an update or something but I have no clue how to get BC started up.
Heres a picture of Symantec telling me its a virus.
