Change directory of files for security reason

How to change directory of files for security reason? I supose, viruses and vorms after bufferoverflow can do everything, including deleting firewalls like iptables, chkrootkit and others. The script of malicious code must know where security files are stored to delete them. The solution is that everybody change file directory by his teste (customly) and offender NEVER will guess fast program file`s directory to get control on the system forever After changing directory of bin file it can not. Is this possible?
