Hello security-minded folks. I have an issue. My dad has a computer and he gives away personal information to everyone who asks for it. He clicks just about every ad he comes across and puts all his information in and when they call he gives out credit card info and other personal info on the phone. We can't make him stop though he always promises never again, but he never remembers saying that. He's already had his identity stolen once and that was a huge deal. He had to go to get lawyers, sue businesses to get his credit repaired, etc. I would like to get a firewall or other solution that would block him from putting his personal information into forms and emails. We have both windows and mac computers in the house and we can limit him to either one of these if need be. In not really a mac person, but I did put an adblocker on his mac. That will help a little bit. But we need some kind of full protection. Thanks for any help you can give.
