Abstract: The present invention protects a computer user from exposure to offensive materials from the Internet or other sources, by allowing a user without any computer knowledge or experience to determine if the computer has been exposed to offensive materials. The present invention does not require any installation and does not leave any recognizable traces of it being executed. It collects all the viewable files and all files having offensive words, based on a pre-compiled list, in them and allows the user to review and delete these files. The files are collected from all directories on the attached computer disks without regard to their access control status, e.g., hidden and files marked deleted are collected as well.
