I got a question from one of my users-- turns out they needed a Flash upgrade for their browser, so I ran the install. This is a pretty regular routine; I run the installer, look and double-check for opt-outs (e.g., toolbars and "services"), etc.
Imagine my surprise when-- as part of what was labeled an "urgent security update"-- the update installed Chrome on the machine, without confirmation, request, or even a smug little after-the-fact pop-up! I just saw the short-cut suddenly appear on the desktop, and had to go uninstall it.
Now, I got nothing against Google creating a new browser, or even with Adobe from trying to "encourage its use", but I'm pretty peeved at unsolicited software installing itself without my permission. It's no different from malware, especially if it then requires security updates to keep it from being a back door to OTHER unsolicited installs. I didn't ask for it, didn't want it, and wasn't even told it was "bundled".
Shame on you, Adobe. And Google, for being "especially evil".
