A must have: siteadvisor

With this siteadvisor installed on your PC, you'll never have to worry whether to click a particular site or not. Just download this McAfee SiteAdvisor. After downloading the siteadvisor, a small button appears on the browser toolbar which turns green, red or yellow -depending on the reliability of the site. And when you search with any search engine, it would be rated too. The rating is based on 1) the safety of the softwares downloaded from the site (whether they contain any adware\ spyware\virus\trojans and other malicious programs), 2) the privacy of the user 3) affiliations of the site with other sites 4) on the user's satisfaction (reviews submitted to the sideadvisors). It's cool. Go get it.
