Every PDF in my Computer has changed to Chrome Documents

Either last week or the week before, I installed an updated Acrobat Reader.  Now I do not know if it happened then or what is going on.  Today I tried to download and document and save it as a PDF to my laptop.  Everytime I tried it downloaded and saved as a Chrome Document.  I early today, I sent an email to the company believing that they were preventing me from saving as a PDF, but as I'm looking at my files, I see every PDF document on my laptop has changed to a Chrome HTML document and I don't know why or how to fix it.  I went into Chrome and reset the Acobat extension as default and it is still saving every document as a Chrome HTML Document and I can only read the PDF online.  It cannot be saved to may computer as normal.  Can anyone help he understand what has happened or how I can fix this, or is this something new and you can no longer save PDF documents directly to your computer and they can only be read online from the site you downloaded them from.  Please, is you can give me any assistance I would appreciate it, because I am perplexed to find all my PDF documents converted to Chome document.
