A method and system that enables anti-virus scanning protection of a computer system by placing all changes/updates/installations on a system-wide skin and performing the scan and clean operation on the skin before allowing the components to be merged with those of the base system. A system-wide skin is provided, which covers the entire base system of a computer. A complete scan and clean operation is first performed on the base system before a first skin is placed over the base system. Then any new applications, files, or data are installed on the skin, which overlays the entire base system, such that no updates are actually made to the base system while the system-wide skin is present. All subsequent scan and clean operations are conducted only on the system-wide skin, thus significantly reducing the time for completing such operations. Multiple skins may be provided and clean data merged from one skin to another.
