Code emulation allows for virus detection however, it is extremely slow. Emulation works only if it is run long enough. Strata, a software dynamic translator, acts as a virtual machine that mediates program execution by dynamically examining and translating a program’s instructions before they are run on the host CPU. Strata contains no mechanism to detect viruses. In my approach, I integrated a context-sensitive recognizer for detecting viruses into Strata. We discuss time and space overhead of using this technique with Strata. This paper also discuss false positive and false negative rates.
