Sapphires, Maybe the link below will help. Terry Here is a link that might be useful: Configure Firefox and Mozilla to display PDF files (Acrobat 8.0, Adobe Reader 8.0 on Windows)

It does sound like they got reader on your pc now and not the full acrobat. They may have thought they were doing a security update and not realized it was a different program, which would not surprise me for geek squad. here are some options for you. This one is by Adobe Create PDF Foxit PDF Creator CutePDF Writer Best Free PDF Writer Best Free Non-Adobe PDF Reader Have you tried going to control panel > add remove programs and seeing if your program is still listed there? If so if you hilight it does it give you an option to repair? IF it is still listed then try going to your programs folders in explorer and finding the executable file for it and seeing if you can double click on it. IF the program is still on the pc you should be able to get it back up.

If you do decide to remove AR please consider using REVO. Since v5.0, AR has been getting larger and larger while integrating deeper into the O/S. It can be a real bugger to remove with it's own utility if you can at all. I've seen corrupt uninstaller reports when trying to do so. Also, if you do decide to install the current version of AR I would suggest removing v5.0 first. My recollection is during the v3.0, v4.0, v5.0 era all too often those who attempted an overwrite actually ended up with two versions installed via the same folder. DA

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.
