McAfee SiteAdvisor is a browser plugin that warns you if the website you are looking at has any security issues. Installation is easy and the SiteAdvisor website automatically detects which browser you are using so you install the correct version. A simple indicator at the bottom of your browser shows the status of the website you are browsing. A great product that’s free of charge.
From the SiteAdvisor website:
SiteAdvisor was founded in April 2005 by a group of MIT engineers who wanted to make the Web safer for their family and friends. Having spent one too many holiday breaks trying to clean a mess of spam, adware, and spyware from our families’ computers, we decided to take action.
We realized there was a gaping hole in existing Web security products. While traditional security companies had gotten relatively good at addressing technical threats like viruses, they were failing to prevent a new breed of “social engineering” tricks like spyware infections, identity theft scams, and sites which send excessive e-mail.
To address this challenge, we built a system of automated testers which continually patrol the Web to browse sites, download files, and enter information on sign-up forms. We document all these results and supplement them with feedback from our users, comments from Web site owners, and analysis from our own employees.
Our easy to use software for Internet Explorer and Firefox summarizes our safety results into intuitive red, yellow and green ratings to help Web users stay safe as they search, browse and transact online. Our goal is to pioneer a new approach to Web safety and make the Internet safer for everyone.
On April 5, 2006 we announced that we were acquired by McAfee, Inc. Teaming with McAfee will give us greatly expanded worldwide reach, access to McAfee’s leading security technology, and greater resources to accelerate feature development for our many users.
