Marcos, reading Anna's posts as a whole and taking the entire internal context into account, I think that what she means is:
1. When she was trying to copy and paste a certain folder, ESET wanted to prevent her action because in copying the folder, she was moving a file within that folder which she considered a desirable file, but which ESET considered dangerous.
2. This behavior occurred only when she used the trial version of ESET; when she uninstalled it and used the paid version, ESET no longer tried to prevent the copying of the folder holding the maybe-infected file, though at some later point it still tried to delete the file. It wouldn't surprise me if the difference in the behaviors was caused by one of the versions being newer than the other.
It is odd that she couldn't persuade ESET to remember to ignore that file.
Thanks.
