Why are the PDFs saving as an "ePDF" instead of normal PDF?

Already answered above by denisev - this worked for me - Right click on ePDF document, select properties, under "General" tab, where it says "Opens with", click "Change" select adobe acrobat, click ok.

I already had adobe installed but could not understand why it kept saving and opening as an ePDF...telling it to open as adobe acrobat made the difference.

It caused by the default setting of how your PDF opens. Right click on the thumbnail of the PDF file. In the files properties dialog box, click change. Choose Adobe Acrobat Reader or Adobe Acrobat, and then click OK. (If you don't have one of those as a choice, you will need to download the application to your computer first) In the properties dialog box, click OK. That will change you default and they will no longer be downloaded as ePDFs, but as regular PDFs instead.

Saving PDFs from what using what options?

Are you creating PDF files from some application? If so, exactly how are you doing this?

There is no option in Adobe applications for producing .ePDF files. We don't even know what they are. Sounds like some third party application or malware is on your system.
