- I can no longer tolerate the security vulnerabilities
- I’m annoyed by the updates
- I typically can’t use either on my smart phone anyway (and don’t mind)
- And mostly, there are smaller and more secure substitutes
The best tool is Google Chrome, which includes both a Flash player and a PDF viewer baked into it. Best of all, this browser automatically updates and patches itself on a frequent basis, with no interruption. I’ve configured Windows 7 to use Chrome to open all .PDF files, which I think will be all I require.
If I do need a separate PDF viewer, Sumantra PDF Viewer is likely all that I’ll require. This might also be the solution that I deploy to my employer’s 1,200 users.
