Sounds like there is something wrong with what you are trying to download and not an Adobe problem. Make sure you have the latest version of Adobe Reader or try the small free Foxit Reader 2.0 for Windows which works well for PDF files. At least you could narrow down the problem whether file or reader.

Obviously...whatever is going on...it's not simple. As you didn't post what system you have...any pertinent facts about it...what version of Windows you're running...what anti malware/anti virus programs you're running...I'm really at a loss what to advise you at this point, Shaddy. Actually...my best advice would be to send you to a computer repair shop that you know and trust. Recommendations are difficult because I know nothing about your geographic location. I live in the northeast and wouldn't hesitate to use the local Staples computer repair service if my private source was no longer available...or if I couldn't root out and correct the problem myself. But beyond that...I'm of little help. The fact that all your PDF files are now zipped is a concern. I do hope that you have backed up your files...have them stored in a secondary location. The corrective answer to your systems problem may be simple. You could have a series of unrelated small glitches that together are causing a major issue but it's nearly impossible to discover it or them and/or help with it given the information known so far...and not being able to have a hands-on approach. I could recommend that you do a clean install of whatever Windows [or other] program you're using...if you have the original program disk...but in doing so, you'll lose all your files. If you've backed them up prior to this...you can always add them back into your system once you've done the re-installation. I'm sorry, Shaddy...but I suggest the best approach now is to seek hands on professional assistance if you don't want to re-install your system.

Tag team spam setup question. https://www.google.com/search?q=When+I+open+the+pdf+in+Acrobat+Reader+6+I+get+the+error+msg+%22+An+error+occured+while+openeing+the+document+%28114%29+%22.&gws_rd=ssl Same ancient version of Adobe. Same wording. Same misspelling. Same abbreviation. Same unnecessary spaces within the quotes. My guess is that the "answer" will link to either "f i x t o o l b o x . c o m" or "f i l e r e p a i r f o r u m . c o m". (or a legitimate site that links to either of those) Will this post prevent them from posting the spam answer? Probably not. I doubt they speak English and the answer will be a paste.

I have a Canon LiDE700 which has four function buttons. One is specific for PDFs. "Scan" saves as a .jpg. "E-Mail" saves as a .jpg of smaller size & resolution for an e-mail attachment. "Copy" scans & prints. I have Paint Shop Pro (slightly older version than is current) which interfaces directly to the scanner to scan/import, then the resultant image can be edited if desired, and saved as any graphics format that PSP supports. The function in my version is under File / Import / TWAIN / Acquire. Can also add a scan button to the toolbar (which icon looks like a hand-held scanner). Other graphics editors may also directly support a scanner. (TWAIN is an acronym for [really!] Technology Without An Interesting Name, which is a standard for communication between computer software and image input hardware such as scanners.) I have Adobe Acrobat Pro (not free, different than Adobe Reader) which can convert/save a .pdf to many other formats including .jpg. Reader DC can't do that, it can only convert to Word, Excel, and Powerpoint (and maybe those only if the respective programs are also installed), and to a text file (.txt) or a Rich Text file (.rtf) ... not any images-type files. Since you seem to have some graphics editing experience, perhaps view the .pdf in Reader, do a screen capture of it, and crop/save the individual photos to .jpgs.
