Don't mix exploits with viruses -- they are different.

Exploit is where application does something very unexpected due to a
bug.

Virus is where machine works correctly, but user does something
stupid.

For exploits, randomization + patching + compartments seem like a
solution. We should be working on "how to confine openoffice.org so
that it can't do much damage" instead of "how to detect .doc documents
that makes openoffice.org do something unexpected".
