I am looking for a free Pdf viewer (not so fancy). The only thing I need to do with the Pdf viewer is to view Pdf files, zoom in-out (just basic features). Most importantly, it should not keep checking for updates or doing some tasks in the background.
Cool Pdf Viewer fullfills all the requirements except that it is not stable (crashes, hangs, unstable, scrolling slider doesn't work) and it is not free for industrial distribution.
