I don't see any advantage for Norton doing this what so ever. So they already have actual products that do someting, anti this, anti-that, to what end does partnering with Ask, notorious toolbat bundler extraordianire do for them?
Norton blew it with their Safe Web ratings forcing people to buy software instead of offering it for free like SiteAadvisor, Trusthound and many others. No one needs to pay for that service. I guess maybe they think the 4% that Ask has in the search market will do something for them?
They should have had an free version and Pro. This would have increased their reviewer database enourmously. Then they wouldn't have needed to get into bed with Ask.
