ABSTRACT:
The file context of a target file to be scanned is determined and the scan level for the file context is determined. Generally, the security risk for each file context is assessed, and the scan level appropriate for the security risk is associated with the file context. The target file is scanned at the scan level. Accordingly, a target file having a file context indicating that the file is a high security risk is scanned at a high scan level, i.e., is subject to a maximum-security scan. In this manner, high-level security is maintained. Conversely, a target file having a file context indicating that the file is a low security risk is scanned at a low scan level, i.e., is subject to a minimum-security scan or no scan at all. In this manner, high security is maintained while at the same time maximum performance is achieved.
