Well, this is of course not correct - a format is never necessary to get rid of a virus - boot sector or otherwise. However, Azusa is rather problematic, as it does not store the original PBR anywhere - it simply replaces it. (It is easy to remove Azusa from diskettes) Suggested solutions: 1) Use NU to zero out the PBR, then use NDD to rebuild it. 2) Use a disinfection program which can replace the PBR with a "standard" PBR - such programs exist. - -frisk
