ABSTRACT:
A computer system includes a security subsystem which is able to trustfully track which files or storage areas of a storage device have been altered since a last virus scan. The trusted information can then be used to accelerate scans for undesirable code or data such as viruses and invalid or corrupt registry entries. In the case of viruses, files or storage areas which have been altered are scanned against a super-set of virus definitions. Unaltered files or storage areas are scanned against a subset of virus definitions.
