To begin I did not realize this was even possible with Windows 7 as I always need to acknowledge a new installation of software.
I use another pdf reader and uninstalled Adobe Reader a long time ago. Last month I saw it on my computer and uninstalled it, only to have it appear the next day! I uninstalled it again and this time cleaned the registry of all related entries and setup a block in security for the entire adobe.com site. The next day it was back. Please help as I can't find any related items on an Internet search.
