Well, I've gone through a good few PDF readers in my years but I finally found one that I like! Here are the ones that I've tried:
Adobe Acrobat - Bloated with a nice combination of security risks all over the place
FoxIt Reader - Started off great, now is bloated and likes to try to install toolbars
Sumatra PDF - Freaking awesome! TWO files (the uninstaller and the executable) and 1.4MB Might not have all of the features of the above, but it has worked on everything I have thrown at it!
Download Sumatra here.
