I have some encrypted pdf files that have no problem and in my last windows, I could open them easily with Adobe Reader 9.2 and other pdf readers.
But now, I can only open non-encrypted pdf files and one encrypted file with Adobe Reader. every time I open almost any encrypted pdf, it closes itself.
Also, when I try to search a folder for a keyword with Foxit Reader, once it closed.
This is not related to Adobe Reader, because I have the same problem with Word 2007. When I open a document, sometimes it closes instantly and sometimes it closes after a few seconds and sometimes it is stable.
My windows is Fresh. I have installed it a few days ago. I have ESET Smart Security 5.2 and I have updated it today.
