I downloaded all three programs and then Googled, "Free Screensavers." Finjan warns if there is malware in the page itself or it's safe to enter. SiteAdvisor doesn't seem to analyze the page but it warns about bad downloads from it and when Finjan states a page is good or not good, the SiteAdvisor is also warning about downloads from it. The page is probably safe to enter when both programs checkmark it. LinkScanner on the other hand, always shows a green checkmark even though the other two programs give warnings stating that the page is unsafe for browsing or downloading. I think Finjan and SiteAdvisor working together can be a good thing but I'm not so sure about LinkScanner being an effective tool. I hope others try all three programs and comment about what they think.
