I’ve been using Blue Coat’s K9 Web Protection for years. It is free filter and takes just a minute to install. I also run it on my work laptop to protect me from accidental exposures to bad sites. It allows you to set degrees of protection and has a password to override its filter. You can view a history of visted websites and allows you to put time limits as to when your family members can use the internet. If you think you don’t need it…..you’re wrong.
If you don’t have it, go get it at www.k9webprotection.com.
