Downloading and running pwdump and ophcrack

Greetings everyone,

 

I am an information security student and Norton is preventing me from downloading, installing, and running certain programs such as pwdump and ophcrack.  I am fullly aware why Norton would consider these programs threats to my system and not allow them but I really need to be able to use them to aid my studies about  information security and ways hackers use to penetrate systems.  I tried listing pwdump and ophcrack as allowed programs within the Norton configurations but this does not seem to actually do anything.  How can I tell Norton that it is ok to download and run programs such as these?

 

Thank you for any time and consideration with this matter,
