Hi Guys!!
I have tried everything ranging from Mcafee Siteadvisor to WOT(Web of Trust) to find the BEST among the "Safe Browsing Tools"!Finally, my choice has struck with Linkscanner Lite( AVG has now started offering the same as a standalone product as well). Its way-way fast & receive updates on every alternate day as well!
What's your choice? & YES to tell you the truth, just for a CHANGE sake, I have installed "Finjan's Secure Browsing" extension within FF within Ubuntu(Version 9).{Alas, Finjan's webpage has not been updated since Year 2007 & don think they r too enthusiastic about the same}
Please come up with your Choice....!
