All of a sudden all my saved PDF files in Windows 10 have been change to Avast HTML.Document - As well as when I scan files to .pdf on a usb stick they show up as Avast HTML Documents... very frustrating and haven't found a solution, hopefully until now, on here :)

Can right click on a file and select "Open with" the default viewer.
Or open settings > Default Apps > Choose default apps by file type.

You may already have figured this out. But I just got a laptop with Windows 10, and the same thing happened to me. I fixed the problem by doing the following:

1. Right-click on any Avast HTML document
2. Select "Properties" at the bottom of the drop-down menu
3. When the window pops up, it should be on the "General" tab view
4. In this pop-up window, look for "Opens with:", and you'll see the program currently associated with the file (in this case "Avast HTML Document"); next to this will be a "Change" button
5. Click on the "Change" button. When another window pops up asking "How do you want to open [current program] files from now on?", click on "More apps" under OTHER OPTIONS and select Adobe Acrobat.
6. Click OK,
7. Exit.

You should be all set. Note: If the "Change" button is grayed out, then that's another issue, and unfortunately I don't know how to work around that.

Well, I have hundreds of Adobe PDF files. I think it is Avast, rather than Window 10, that changes them. ALL my files are now Avast HTML files. I don't want to have to change them all one at a time. Can I fix all of them somehow quickly? Also, how can I keep Avast from doing this again? I was chatting with Avast and got dropped, so I don't think I can count on Avast to help.

So, I changed one file back to Adobe PDF and miraculously all the file that had been changed to Avast HTML changed back! Hooray!

Hi Ken, I had the same problem. I have the free, basic-level, Avast antivirus service and must have pressed an option that converted access to files only through the Avast secure browser. After which so many docs and files changed to HTML documents. I rang the Avast tech helpline on 0800 085 4825 today and they reversed the action and restored all my files and docs to Word.

I had the same problem awhile back. All I had to do was save as one of the Avast files as an Adobe .pdf. All of the Avast file turned back into Adobe files when I did that. I haven't had a problem since. Try it. If it asks you any questions about setting Adobe as the devault, say "yes."

Thanks... simple and to the point.
