Here in Australia wednesday 16, got up first thing this morning and opened the world of warcraft launcher and it started downloading an "updated tools" which happens quite often and is usually only a few MB at most and in 3 years of using NIS and playing wow norton detected this as a suspicious activity and REMOVED! the file, fixing it was simply a matter of clicking on "show details" in the little red warning box in the lower right corner of vista 64 bit that popped up and selecting options and restore and exclude this file from further action.
While I have easily fixed this I thought the people at norton should know that the launcher has installed an updated tools dozens of times and this is the first time this has happened.
