just bought my son a laptop and he likes playing scrabble etc online, also has to do homework by looking up stuff on google. my worry is what he might find that he shouldnt see (even though I will be with him when doing this, you never know what might pop up!). Can anyone recommend some software to block all porn sites etc and other malicious stuff? Dont mind if its subscription based or free or buy out right. There's lots out there but not sure what to get? Thanks in advanced.
