McAfee SiteAdvisor Search Toolbar is a search toolbar which warns you when you are visiting a unsafe website which is infected with a virus. McAfee SiteAdvisor is not an Antivirus. It is just a toolbar which warns you of known dangerous websites like virus infected, scam, frauds, and un-secure sites which McAfee has discovered. It works similar to the Norton SafeWeb Toolbar, and other security based toolbars like AVG linkscanner tool bar. However, you do not have to install McAfee Antivirus to use McAfee SiteAdvisor toolbar.
I like that it was easy to install. All I have to do is run the installer for Siteadvisor, and it will be installed on all compatible browsers for SiteAdvisor like Internet Explorer, FireFox, and Chrome.
SiteAdvisor also displays badges next too each website link on search results for Yahoo, Google, Bing, Ask, and AOL search engine results when you search for websites. If you hover over the SiteAdvisor badge on the search results with your Mouse cursor, you can also see a short summary for safety of the website. You can also click the badge on the SiteAdvisor toolbar, to view the safety summary of the page which you are currently on.
Red means dangerous, Yellow means caution, Green means safe, and Gray means unknown for the badges in the search results. Also, if you visit a website by using the address bar, or a bookmark to go to a website, SiteAdvisor will also advise you if the website is safe or not.
McAfee SiteAdvisor also warns you of unsafe downloads if the website link which you are downloading from.
If a website is not safe, a pop-up message will warn you to leave the website because it is unsafe.
The McAfee Toolbar is very easy to use. All I need to do is install it, and let it run. In Internet Explorer, and Firefox there is a search box, but in Google Chrome, there is just the McAfee SiteAdvisor badge which tells you the safety ratting of the website. The Toolbar for SiteAdvisor is located on the top of the browser for Internet Explorer, on the bottom for Firefox, and on the top right corner for Chrome. The Toolbar is only about a few pixels tall like most other toolbars for IE and Firefox. In Chrome, SiteAdvisor is only a small badge, so it uses very little space in Chrome.
McAfee SiteAdvisor toolbar service only uses 2MB of RAM according to Windows 7 Task Manager, and does not slow down Firefox, Chrome, or Internet Explorer in my experience. McAfee SiteAdvisor works for the latest version FireFox 4, Internet Explorer 9, and Google Chrome 10. I tried McAfee SiteAdvisor in Internet Explorer 9, Chrome 10, and FireFox 4, and McAfee SiteAdvisor did not slow down my web browsers to a noticeable level.
You can download McAfee SiteAdvisor toolbar from siteadvisor.com

McAfee SiteAdvisor is not a replacement for an Antivirus, so you should still have an Antivirus program installed on your computer.
