Dale,

 

there are some browser add-ons that try to "weed-out" the good pages from the bad.    these include:

 

1) McAfee's SiteAdvisor  http://www.siteadvisor.com/

 

2) TrendSecure's TrendProtect  http://www.trendsecure.com/portal/en-US/tools/security_tools/trendprotect

 

3) FireTrust's SiteHound  http://www.firetrust.com/en/products/sitehound

 

the first two have an option to highlight search result links, using a color-coded system, which roughly corresponds to Green=safe, Yellow=questionable, Red=unsafe.   

[Read their documentation for a precise explanation]

 

the third one actually prevents you from accessing (what they consider to be) a "bad" page, unless you explicitly consent to enter.

 

You can load either 1 or 2 (but not both), and optionally together with 3.

 

HOWEVER:

I personally find all three of the above severely deficient in their ratings:   I've encountered safe sites that have been "red-flagged", as well as "bad" sites that were given the green light.   In short, it's probably better than nothing... but I'd still use my own judgment [and common sense] about whether or not to visit a particular site.
