My sister, who is computer illiterate, has asked me to take a look at her teenage son's web traffic to see what sites he has been using. He is not very computer literate either, but his history in Firefox is suspiciously low on the number of sites for the amount of time he spends online. Is there an easy way to record visited sites that wouldn't easily be noticed? I checked the DNS cache (ipconfig /displaydns) but didn't see anything suspicious yet. I would like to see all his traffic after a few weeks. Any suggestions? A free method would be preferred.
Or even better would be a simple program that would let me see what he is doing remotely. (I would have access to the computer initially to install any software and set up firewall exceptions - I'm just looking for a SIMPLE way to do this.)
