Is there any software that I can use to keep an eye on what my kids are doing online? And, if it has the feature of block some unwanted webpages, that would be better. I have ever used this Mac keylogger, but a little expensive. A friend online suggest I use this Keylogger Mac or the Mac spy. But they can't be used as a web filter. Do you have any better ideas? I am not interested in evil virus and cheap ones will be appreciated. Btw, we are on Mac OS X.
