Adobe plugin for PDFs from Word etc
adobe acrobat 7 update
It is able to monitor Internet browsers. If company's were ethical, and never compromised the clients privacy these helpful programs would be okay, Why can I not be permitted to uninstall Acrobat Update? If it is not absolutley necessary for the program to funktion I don't want to be forced to have it running, for what ever it is really doing.
I can't immagine why anyone would find the Acrobat plugin dangerous. You need this running for the program to work correctly.
seems to be harmless. used for Adobe plugin. just be careful
