    A virus/worm can damage only files owned by the user, so with
or without binaries owned by the user who has run the virus/worm
in her/his home, it can make the same damage. A virus/worm can make
~/.bin and also export PATH="~/.bin:$PATH" from your ~/.bashrc.
What's the diference? The only way to stop the user from running
untrusted applications is to mount /home and /tmp with noexec,
which breaks some applications (rpmbuild, mc) :(
