I used to be able to clear my history (clear all history) but did't have to re-enter account numbers each time I entered a site. After a nice geek fixed a malware problem (I could get emails but couldn't sign on to the internet using firefox, explorer, etc.) I can't clear anything without having to sign in each time. I am really clueless about how to secure things. I don't understand which items to NOT clear -- cookies, cache, etc. HELP!!!! The diagrams don't make sense.
