The wizard tries to detect the tools, but the user can overide the preselections. Then the user can decide what funtionality shall be supported by the created filter rules. The wizard will append the created filter rules after the last existing rule to keep possible conflicts with existing filter configurations minimal. Anti-virus support was added by Fred Emmott The configuration for the tools to get checked and set up is read from a config file. The structure of the file is as following:
