AcroRd32.exe does not start automatically (unless you have it in your startup items for some reason).
If you view an online PDF from your browser, that will start AcroRd32.exe, and I believe it will remain running until you close the browser.
Any way to prevent this damn thing from starting?!
You can remove Adobe Reader from your system.
It remains open even after I close the browser.
I believe that was my point.
I've already downloaded other free pdf readers.
Just a matter of time.
