Q. As a parent of young children, how can I best protect them from undesirable content online without banning them from the web? You have several options, among which KidZui is perhaps the best. You can also check out the parental controls built into your PC operating system. Another option is to install web filtering software, such as Net Nanny. You could also consider installing a browser designed specifically for children, such as Buddy Browser ( www.buddybrowser.com ) , or a browser add-on like Glubble for Firefox ( www.glubble.com ) .

Q. Who is behind KidZui? KidZui's founders include Cliff Boro, who began his career on Wall Street, and then founded and ran Infogate (which was sold to AOL Time Warner in 2003). The senior management team includes editor-in-chief Deanne Kells, former editor-in-chief of LeapFrog, the educational technology company. Tom Kalinske, former chief executive of Mattel and educational company Leapfrog, sits on the company's board.
