Not sure if the website you are visiting is a safe website. Will you start getting alot of spam. Will the website try download spyware or adware while you are browsing the website. What if you could be warned of trouble.

McAfee recently purchased a company called siteadvisor and is providing their product free of charge.
It is a small utility that will tell you using colors Green=Safe, Grey=Caution or Red=Danger as to whether a website is dangerous and will create spam, download spyware and create other problems that you may want to avoid.

The tool is available for both MS Internet Explorer and Firefox. If you use both web browsers then you will need to download the utility for both browsers as they are two separate tools.
