No pdf password remover can open them. Even antivirus software can not scan them and report them as viruses.
Then I noticed those files are copied by Adobe Acrobat Reader when you install the software onto the computer. And all computers with Adobe Reader v.6 will have those files. So, I made sure they are not viruses.
Then I searched furthermore to find out why those files are password protected. And I found out that adobe uses those files for specific purposes such as advertisements and that you could disable those functions inside adobe menus.
However, What I wonder is can a pdf file which will include text or pictures function as an exe file or can a pdf file can include codes that could function as an exe file?
Regards..
simply disable the execution of JavaScript within the Adobe software. In your Adobe product, go to Edit–Preferences–JavaScript, and uncheck the box next to Enable Adobe JavaScript. or maybe you can solve the problem using linux. Kolay gelsin.

That suggests that the data streams in the PDF are encrypted. There are several types of such encryption … the default type is not very strong and can be broken by brute force.

A short answer is that PDF files may contain a type of JavaScript, which is excutable code. For the exact operations that are allowed here, see the ref. man.
Additionally, there may the usual vulnerabilities involved with interpreters (PDF is an interpreted format) buffer overflows, etc.
An easier approach may be to find out what version of PDF reader you have, and then look for security announcements concerning it. (The vulnerability database at Secunia is often useful.) Recently Adobe released the Acrobat X reader in response to security problems with earlier versions of Acrobat.

Yes.
