I'm using wireless iternet supplied by my roomate. They have the router and service, and have given me code for use on my computer. How do I hide my web history in a way that at least they don't know what it is if seen?
Depending on the make and model of the router, they'll have difficulty unless they can get into your computer. You could use your browser settings to delete all content on exit. If you're considering downloading illegal content, you should be aware that it could land your roomate in trouble and tyrying to prove it wasn't him.
