Fenris是一个检测并把高层次的语言结构做成文档的多功能故障检测器、调试器、代码分析工具。它能回复符号，把程序执行流绘成图，检查内部运行情况，恢复符号表，并处理反调试保护。它有一个命令行接口和一个类似SoftICE的GUI与Web前端-Fenris is a detection and high-level language structure made of multifunctional document fault detection, debugging, code analysis tools. It can restore symbols, compose program execution flow map, check their internal operations, restoration of the symbol table, and to deal with anti-debugging protection. It is a command line interface and a similar SoftICE with the GUI front-end Web
