Internet Security will not allow a program to work

I bought the ClickBank PDF converter for the computer and I get reader to convert it say Security Dectected you must remove or cancelled. They refunding my money but I need something.

 

But what should I do if if I get another program and it does the same thing. I have Windows 7 on a 64 bit computer.
