If the above response is accurate, the things you are requesting that Norton 360 display are already presented by the Nero installer as you install the program (this is typically true of bundled software in general). There is a legitimate business partnership between Nero and OpenCandy. Users have the choice to opt out of the OpenCandy installation, which is one reason that OpenCandy is considered to be grayware, not malware. As long as the user is presented with the offer of the bundled software and given an opportunity to decline, most third-parties, such as Symantec, are going to be unwilling to insert themselves into this situation and infringe upon the advertising arrangement between Nero and OpenCandy.

Symantec recently posted a blog about Grayware in the Mobile Software Marketplace here:
http://www.symantec.com/connect/blogs/grayware-casting-shadow-over-mobile-software-marketplace
With regards to your 'legitimate business partnership' comment above, that blog states:
What can be done about grayware? Because it doesn’t cross the bounds of illegality, antivirus firms usually can’t block it. Occasionally it is removed from official mobile marketplaces such as the Apple App Store or Google Play because it violates terms and conditions.
Knowledge is the best defense. In the same way that PC users are now a little bit more wary about what they install on their computers, smartphone users should take a moment to consider what they’re downloading and look into what permissions the app is seeking.
There are also a number of tools you can use to help identify which apps may be taking liberties with your smartphone. For example, Norton Spot will scan your Android phone for aggressive ad libraries that may spam your device and identify the apps associated with them.
The behaviour of the Norton Spot product, however, seems to contradict both your statement and Symantec's position that "Symantec, are going to be unwilling to insert themselves into this situation and infringe upon the advertising arrangement between Nero and OpenCandy".
Take a look at the description of the Norton Spot product below (emphasis mine):
Norton Spot scans for advertising networks that may spam your device. Identify apps that don't respect your privacy and remove them. Monitor for intrusive alerts and aggressive mobile advertising (madware), including apps that constantly push ads to your notification bar, create unauthorized desktop shortcuts, and secretly collect your personal information. We spot the madware, you decide whether to keep it.
It's your device. Take back control with Norton Spot.
FEATURES
• Scan and identify apps that display intrusive ads on your device
• Remove app spam and aggressive advertising networks
• Catch ad networks attempting to hide from ad detectors (ad module obfuscation)
• Sort apps by potential annoyance levels
• Identify which apps are collecting your personal information without permission
• Uninstall apps that don't respect your privacy
PC users expect all of the features of the Norton Spot product, listed above, to already be an inherent part of the feature set of the Norton product that‘s protecting their PC. For PC users, knowledge can be the best defence only if their Norton product proactively alerts them about what's contained in the software bundle that the user is about to install. If Norton Spot can state 'We spot the madware, you decide whether to keep it', then why don't the Norton PC product's present a notification stating 'We spot a software bundle/grayware installer; you decide whether to keep it' when the Norton PC product encounters this grayware?
Put yourself in the OP's shoes. Do you think a Norton product notification like that would address this issue for Norton PC users? Wouldn't a Norton product notification like that encourage users to take additional care and read everything presented to them during that software installation process?
