You might try out Foxit reader before Adobe. I've been using it for 3 years both at work and home. It's a lot less bloated than Adobe and when you install it, all you get is the reader unlike Adobe which also installs Adobe Air and Adobe.com.
I timed it once and it took about 6 minutes to install Adobe and about 5 seconds to install Foxit. That just shows how bloated Adobe has become over the years.
