I fix broken websites for a living. So when I remove and clean a site of malware or phishing etc, Google Safe Browsing, Phish tank, SiteAdvisor, Sucuri Malware Labs, SpamHaus DBL, Bitdefender and Yandex (via Sophos) all have great tools to de-list a site in a timely manner.
Norton Safe Web on the other hand is a night mare to deal with. Often weeks and months go by to no avail and their de-listing seems to go to a black hole.
I wish I could give it 0 stars, but 1 star is the minimum.
