I stick with .pdf files

However, that might be bad practice.

With Adobe Reader it's probably even worse, to be honest.

For the past few years I've been using Chrome as a PDF reader (I don't use it as my primary browser, but have it nonetheless). I'm not saying Chrome can't be vulnerable... it's just good to get rid of such pointless software as PDF reader. Especially if the case is the bloated Acrobat Reader (though I think the UX was great with that one).
