My sisters boyfriend has been compromising my machine, he has been going onto these pronographic websites. I have no idea of how safe they are. He thinks i don't know that he has been going on them by clearing internet history, but by using ccleaner i manage to still see. I do not want this compromisation. What i want to do is store visited websites in another place, a folder for example, also i want him to not be able to clear it, i.e, disabling the internet explorer internet history deletion tool, so he thinks oh crap, i can't clear it, and they will see, so hopefully he will stop. Also is there anyway i can do something similar with my wireless network, i have a belkin wireless G router, with several laptops and computers on, is there any way i can block websites using this, so it is in affect for all computers and laptops on the network? Weird requests i know, but he is comprosmising my laptop, which houses thousands of photos, i still have to get these backed up of course, any suggestions on that? Is an external hardrive a good option? Thanks in advance.
