In general, deletion and/or modification of instances of code that are already covered by the whitelist are also disallowed in accordance with a security policy. Accordingly, an executable that is trusted may be allowed to delete and/or modify code instances covered by the whitelist. In general, trust may be coded for a given code instance that seeks to introduce, remove or modify code.
