I'm not sure I should be concerned about this warning?

With some warnings, especially the Potential Stranger and Age-related warnings, you will want more information before being concerned.

Get more information, which you can then discuss with your child:

• For the Adult who friends many children warning, if you already know and trust this person, there is nothing to be concerned about. This warning appears any time an adult has "friended" several children from a social cluster, but sometimes--as in families--this is normal.
• For Potential Stranger warnings, see What does Potential Stranger mean? and If my child doesn’t remember a “Potential Stranger" is it an error?
• For Age warnings, keep in mind that ZoneAlarm SocialGuard's age estimations are dependent in part on the user's self-reporting, so they may not always be accurate.
• Find the user in the ZoneAlarm SocialGuard Warnings panel. You can see exactly which words, links, or age issues are associated with this person.
