had a friend over using my computer.....harmless enough for me most any time. he did some snooping to see what web-sites i had been on and i wasnt sure i liked what he was doing and their was no need for him to spy on me whatsoever he has since returned back to school, many miles from where i live. i now, out of the clear blue , feel a need to watch him or anyone like him on my computer ! i wont be so good to loan out its use again. i do know how to use "tools " to erase web-sites and clear cookies but i believe he clicked on some other sort of tool bar or ??? to get some visited web site info. could someone please tell me , explain in DETAIL, what this might be so i can use it as an eraser if i feel the need to do so thanks wally i use firefox most all the time and use google as the searcher.
