Adobe Acrobat is a family of computer programs developed by Adobe Systems,
designed to view, create, manipulate and manage files in Adobe's
Plug-in from Adobe. It reads documents in PDF format on any platform.
A program from Adobe that lets you capture a document and then view it in its
original format and appearance
Adobe has changed the names of the products in the Acrobat family regularly,
also splitting-up, joining, or discontinuing products. Between version 3 and 5,
Standard and Professional versions were one product simply called Adobe
Acrobat.
As of October 2009
[update], the current main members of the Adobe Acrobat
family are:
Adobe Reader 8/9 Icon
- Adobe Reader 9 (Windows, Mac and Unix)
- Adobe Acrobat 9 (Windows & Mac only; no Unix version)
- Adobe Acrobat 9 Standard
- Adobe Acrobat 9 Pro
- Adobe Acrobat 9 Pro Extended (includes Adobe Presenter)
The latest version
Version 9.0
Adobe Acrobat 9.0 was released July 2008:
[10][11]
- PDF version 1.7 (and prior) supported. There are Adobe extensions to PDF 1.7
for Acrobat 9.
- Product Family includes: Acrobat Standard 9 (Windows only), Acrobat Pro 9,
Acrobat Pro Extended 9 (Windows only).
- Pro Extended Version includes Adobe Presenter and the features of Acrobat
3D.
- The ability to create Acroforms was restored to Acrobat Standard in this
release (in versions 6 through 8, Acrobat Professional was required).
- Enable real-time collaboration of PDFs with synchronized document views and
chat.
- Improved Web Capture for capturing entire web pages or just some parts into
PDF.
- Integration with acrobat.com to enable storage and sharing of PDF
files.
- Personalize a PDF Portfolio with customizable templates for navigation and
branding.
- Compare and highlight the differences between two versions of a PDF
document.
- Insert FLV (Flash) or H.264 video for direct
playback in Adobe Acrobat and Adobe Reader.
- Convert a variety of video formats to FLV for playback in PDF.
- Create PDF maps by importing geospatial files that retain metadata and
coordinates.
- OCR PDFs (Paper Capture) using ClearScan. Adobe ClearScan technology creates
custom Type1-CID fonts to match the visual appearance of a scanned document
after optical character recognition (OCR). ClearScan does not replace the fonts
with your system fonts or substitute them by Type1-MM (as in Acrobat 8 and
earlier versions), but uses these newly created custom fonts. The custom fonts
are embedded in the PDF file (this is obviously mandatory). If the OCR does not
recognize a word with enough confidence, then the image (bitmap) of the word is
shown in the PDF and the text is put above but hidden (same as what is made in
"Searchable Image" mode).
- Adobe Reader 9 drops support for Adobe Reader Extensions 5 and 6 which
permit Adobe Reader client software to save changes to filled-in forms in PDFs.
Adobe Reader Extensions 6.1 and newer are still supported. Legacy PDFs will
still be viewable, however they will open with the warning "This document
enables Reader capabilities that are no longer enabled in this Reader
version."[12]
- On March 10, 2009, Adobe Reader 9.1 was released which addresses a number of
customer workflow issues and a critical security vulnerability while providing
more stability.[13]

critical security vulnerabilities.[14]

of critical security vulnerabilities.[15]
- On July 31, 2009, update version 9.1.3 was released which addresses a number
of critical security vulnerabilities.[16]
- On October 14, 2009, Adobe Acrobat 9.2 was released (added support for
Windows 7 x86/x64 and fixed many security issues).[17]

critical security vulnerabilities.[20]
If you are using a Windows computer and not a Mac, there are several ways to recover a deleted pdf document.
First, though, take a look at the folder named autosave in the web link below to see if there is a copy of your pdf document or not.

If not, provide more information in the comments box - for example, does the pdf document open without an error message? - you stated all new data for 3 days missing so another copy may be in a different location or can be "undeleted" from your computer.
