That almost never happens, and most people don't want to lose that
data by deleting that file.It is far more likely that the profile is
corrupted or the NK2 file set to read only by AV software. Making sure
the NK2 file is not read only and creating a new profile will fix it.
A new mail profile uses the same .nk2 file? That is, the .nk2 file is
shared amongst multiple mail profiles? I'm not saying that sharing
doesn't happen. It just seems contradictory to the purpose of creating
mail profiles.
I have used Norton AV, EzAntivirus, McAfee, and maybe a couple of others
and don't recall every having problems because the .nk2 suddenly got its
attributes changed to read-only. I have, however, seen screwups in
folder permissions under the path in which the .nk2 file is stored (but
those were user errors).
