AcroRd32.exe
(Adobe)
The Adobe Acrobat Reader program itself. Adobe Acrobat Reader will open automatically if you click on a PDF file in Windows Explorer, or if you start it via "Start \ Programs". Adobe Acrobat Reader also gets started in integrated manner if you click on a web page link to a PDF file when you do that your browser starts Adobe Acrobat Reader in "integrated manner" (plugin) and presents you the PDF document as if it were a web page. Once started in this manner, ACRORD32 does not terminate, even when you close your browser, and it continues to run transparently in the background so that it can open faster the next time you click on a PDF web link it will only disappear from your Task List if you do an "End Task" on it, or if you reboot your PC.
