I checked and neither computer has Sea Monkey listed in
Programs and Features.

I ran Agent Ransack(basic) and it found Helper.exe for SeaMonkey

It sounds like creating a clone at this point is a bad idea if I were
to go backwards to fix it because I would be in the same mess as
the guy in the link you gave but how do we resolve the problem ?

I did a search on Agent Ransack(basic) for Profiles.ini and it also
found Sea Monkey

How do I proceed?
