What software license or freeware to tested our exe format

Dear all member,
I want to know, what is the software to tested our exe file after build.
Out there selling some software to protection our exe file from anti debugger-cracking-patching and etc.
Right now I used a freeware like MIW to compressed my exe files but not sure, because I don't know how to test inside my small app.

Please if you guys know what that software is best to tested our exe files.

Thanks.
