Yesterday a friend of mine showed me how to access everything I have done in my computer from websites I have visited, pictures, links, IMs, pretty much everything I do in my computer. The thing is he didn't hack into my computer (I have recently done a restore in my computer about 5 days ago and he accessed data from August 1st), he has never even come to my house before. He signed up for one of those spy softwares (it was not downloaded into his computer)... anyways, how can I block people from checking my personal information? I thought Macs were safer than Windows machines. I am not sure if he did that through IP...Does anybody know a website that offers that service? Isn't that illegal? My main concern is blocking people from accessing my personal information and pages I have visited.... Any help will be highly appreciated.
