Why does my Adobe Reader DC stop working when I click scroll down options?

Question

I used to use PDF Suite 2014 Standard to view pdf files.
However, tonight a message appeared when I attempted to open files saying ..."if the document does not load then the pdf viewer may not be able to display this type of document"
I went to the website provided to download Adobe Acrobat Reader DC.
Although I was able to load pdf documents and fill in forms, the program repeatedly would crash whenever I attempted to click on scroll down options on forms.
Any help is appreciated
....and talk/write slowly for I am not super computer literate.
Regards,
Luisa

 Dear Aedesh, Thank you for your assistance.  I did all that you instructed below, regarding uninstalling, and using the Adobe Reader and Acrobat Cleaner Tool.  I restarted my computer, then installed Adobe Acrobat Reader DC (for Windows 7, English and version: Reader DC 2015). I continue to have the problems: (1) When I attempt to use a scroll down option within a pdf form, the program stops working. (2) If I send the pdf to my iPhone, and I open the pdf, I receive the message "Please wait...if the message is not eventually replaced by the proper contents of the document, your pdf viewer may not be able to display this type of document..." However, when I send pdf's created earlier than 4-28-15, I am able to open in my iPhone.I am able to open on my laptop the pdf's created after 4-28-15, but have the scroll option issue  (thank you in advance for your patience)Luisa
