detect scam

Internet is filled with scam, for every 1 good site there are about 100 scam sites. Joining a scam site is highly irritating. I use the following strategies to detect scam:-

1- Type the name of the site in the google search box and put the word "scam" along with it.

2- Use McAfee Site advisor( it is a free software). For greater protection, you can use the paid software Site Advisor+.
