I would avoid trying to download a free copy of somebody's swiped copy of a

Books shouldn't (implicitly) contain executables. So, the only potential
for an "infection" would be a buggy reader implementation. In much
the same way that *photos* don't (implicitly) contain code and any
exploits are the result of poor "viewer" implementations.

Contrast this with PDF's -- which *do* contain "code" (albeit postscript
and/or adobe script).

The "swiped copy" issue should be one of morality/legality. Would you
want someone stealing *your* work?
