A few weeks ago McAffee on my machine detected and deleted a file in my Downloads directory. I didn't recognize it, but I haven't had a virus in years so I did a search for the file name and found that it was a copy of the Character Builder back from when it was still in beta.
I don't actually use the Character Builder (and if I wanted to I would've downloaded a recent copy), so I didn't much care but I think it's a false positive. I've had that file on my computer for months (maybe even over a year) and McAffee never had problems with it before.
