Add Encrypted.PDF in the clean words

[datumbox]

Encrypted PDFs are marked by ClamAV as threats and Clamtk does not offer the option to ignore this on the GUI (#66 ):

/path/to/encrypted-doc.pdf: Heuristics.Encrypted.PDF FOUND

Unfortunately the flags passed on /usr/bin/clamscan are hardcoded in the Scan.pm source file and there is no way to change them. This PR provides a quick & dirty fix and treats encrypted PDFs similar to encrypted ZIP/RAR files by ignoring the warning and modifying the clean_words variable on the aforementioned file.

Hi,

Thanks! It will be in 6.04 which should be released this week.

@dave-theunsub Hope you are well. :)

I saw you released v6.04 couple of days ago on gitlab and I saw on the release notes that the Encrypted.PDFs are no longer considered a threat. I had a brief look on the commits but I could not spot the changes. Could you confirm that there are baked in? Thanks!!

Hi @datumbox ,

I'll have to check to see why the lib files are not reflecting the changes, but the released programs seem to all have it:

            'OK',  
            'Zip module failure',  
            "RAR module failure",  
            'Encrypted.PDF',  # <---
            'Encrypted.RAR',  
            'Encrypted.Zip',  
            'Empty file',  
            'Excluded',  
            'Input/Output error',  
            'Files number limit exceeded',  
            'handler error',  
            'Broken.Executable',  
            'Oversized.Zip',  
            'Symbolic link' );  

I also removed functionality like --alert-encrypted-archive --alert-encrypted-doc from the scan, which is basically the same thing.

Thanks, Dave M

I see that you passed directly the changes on the Gitlab repo. Thanks for fixing it. Closing the PR.
