And most malware runs an exploit to install itself, it doesn't require the user to run an installation program. So typical attack vectors are: network services, documents/media files (.pdfs flash etc), and all the usual web stuff. As stated earlier buffer overflows against Gentoo would be a nightmare to write due to the system variability....RHEL not so much.
