I've read your blogpost, fun & interesting reading.
I can give you one tool to help you protect (besides Avast Home with PUP-P, Chrome) against overlooking check-boxes...
http://Browserprotect.org.
Original site might give problems with Download Master*, so mirror download (probably with toolbars?:>), here: ptf.com/download/browserprotect/6673214/
Copy-Paste:
" Avoid Browser Hijacks.
BrowserProtect Premium keeps your browsers safe from homepage, search providers, extensions and other hijacks.
Easy, comprehensive and FREE anti-hijack browser protection for Microsoft Internet Explorer, Mozilla Firefox and Google Chrome."
Karma!
