Here's a very practical way to mark Internet Safety Month (June): free computer-security support for families. But you need to act quickly: Trend Micro will supply $100 worth of security diagnostics and advice to the first 1,000 people who sign up tomorrow (June 15) at FreeDayofSupport.com. Of course, this isn't that great if you're a longtime Norton or Kaspersky user, but it's great if you're not sure how well-protected a family PC is or it's running unusually slow these days. Trend Micro says those first 1,000 registrants will get diagnostic tests and tune-up and a sesh with a Trend Micro security expert, who will walk you through recommended actions and services aimed at maximum computer efficiency and security. Ask that expert lots of questions. In fact, get your kids involved – they might have some important kid-specific questions for secure PC use. For more details, check out the site or this press release. That's a short-term free offer. A long-term one for kid as well as PC security is Norton Online Family, designed to promote family conversations around kids' Net use, which is always good (helps develop the life-long "filtering software" in their heads). For a quick, at-a-glance check of kids' online presence which is also free (but has a subscription version), there's SafetyWeb.com.
