One thing, I don't like is "Link Scanner", which installs without asking for permission.
I use McAfee Site Advisor, which gives you much more info, then AVG's Link Scanner.
If you disable it in AVG, it displays stupid "!" mark on AVG systray icon.
Fortunately, it may be disabled from within browser.
It's incompatible with FF3, which I have on XP, so it doesn't kick in, but it's still listed in Add-ons, as incompatible.
I'm pretty sure, it can be removed through profile listing. I'll work on it.
