password

Hi. I might be asking in the wrong area, but I have just registered and would like to obtain the password needed for the on-access protection control so I can change the settings

Something strange. By default no password is set.
The only password that should be there is one that you set yourself.

Someone else may know how to reset it.

Are you the computer administrator (or logged as a common user)?
Uninstalling and installing again will reset this password… you can use the same registration key again.
