I have used Norton Anti-Virus 2010 and it has a feature called Insight that deals with new unknown files by looking at how the rest of Norton users dealt with that file. If most users said it was unsafe, it was regarded with caution and if most users said the file was safe, it would be regarded as safe.
Also, you could opt out of Norton Insight, meaning it won't upload any details about your system or files, but you still can use the community approach and still get all that Insight feature working.
How does the avast! Community IQ work in comparison?
It seems to me that Avast just uploads any suspicious file automatically to Alwil and that's about it. It doesn't help users figure out if the file is dangerous or not.
Also, you have to have the feature enable to get any of the benefits, unlike Norton Insight mentioned above.
So in total, is that feature useful at all in the way ir currently works? Or does it need a change in the way it works similar to Norton 2010?
