File and folder protection from being read/write/modify/delete

This feature is not generally seen in antivirus or internet security. But I believe it is very good feature addition in any internet security. Afterall its all about security.

There needs to be an addition of files and folder protection. Its function will be to protect specified files/folders from being read/write/modify/delete. This function will be password protected.

Ofcourse what a user will try to protect would be very important to that user. So  this will feature will add an extra layer of protection to those important files/folders. A win win proposition.
