OK so I got sick of McAfee SiteAdvisor the new layout of their site is horrible and not user friendly, the button in your browser interferes with the aesthetics of the browser. SO now I have replaced it with WOT.
WOT is a free Internet security addon for your browser. It will keep you safe from online scams, identity theft, spyware, spam, viruses and unreliable shopping sites. WOT warns you before you interact with a risky website. It’s easy and it’s free.
The best part about WOT is that it’s community driven and not rapped up in the interests of a company like McAfee.
