  Unfortunately, a smart virus author could preserve the modification
date.  So this wouldn't work 100% of the time.  The rest of the time
it would work, but would be too much work, I think (some programs,
like WriteNow for instance, mark files as modified even if they've
only been opened).
  Nice try though.
