Lots of smart people agree: Parents concerned about what the children might be doing online should consider a free, simple tool that has a great added value of making your internet connection faster and smarter: OpenDNS.
I’ve been using OpenDNS for years and can testify that it speeds up browsing, and it practically eliminates re-directs to trashy web sites posing as legitimate search result pages.
Now some surprise news about PC security: Many of the same smart people agree that Microsoft Security Essentials (a free download) is an excellent option that may enable you to cancel your annual subscription to Norton or McAfee and the like. Long-time Microsoft bashers (like me) are shaking their heads over this one. It seems that Microsoft got something right for a change. MSE reportedly does a fine job taking care of viruses, spyware, and malware.
I’m still partial to Avast! (free) for my anti-virus solution, but if that should go away I’d give MSE a good long look (despite its dubious provenance).
