I would tend to agree that eradicating all viruses would be difficult
because so many have animal "pools" that they break out of. You might
do in space as we migrate there. However, it does seem feasible
to design genome and immune system "patches" that make us effectively
immune to all known viruses (anti-sense RNA for the viruses, pre-programmed
antibody manufacture, etc.).

Are you refering to all the old data on my hard drives?

Well since retroviruses seem to play an important role in genome
shuffling, I would imagine that if you engineered in "anti-retroviral"
patches (an anti-retrovirus virus anyone?) that you would slow down
evolution signifcantly. Whether that is good or bad depends on how
much of a preservationist vs. laissez faire type you happen to be.
