In its June issue, Consumer Reports rates 11 filtering software products designed to block pornography, most of which can be set up in minutes. The magazine also offers advice to parents who are trying to better protect their children online.

It gave its top rating to Safe Eyes (2005), $50 from SafeBrowse.com. It "offered the best combination of protection and minimum interference" with search-engine results.

Parental Controls (9.1) from Microsoft, which comes free with MSN service, "provides nearly the same protection as SafeBrowse.com and lets parents set multiple age levels. But it lacks most features offered by other high-rated models.

For Mac users or families with young children, AOL Parental Controls (9.0), which comes free with AOL service, "offers the best pornography-blocking and time-management controls, plus the ability to customize for different age levels. AOL also offered the best protection among Mac-compatible products."

The full report on filtering software is available free on www.ConsumerReports.org. For more advice, parents can go to NetParents.org and/or the American Library Association.
