Proxy or filter program

Hi,

I have a user that requested a filter for her web browser that blocks all but a few specific web sites (some of them encrypted). The user has a problem with browsing the web and classifies herself as an addict.

I want something FREEWARE to help save her job!

Thanks,
Pat

What about using the content advisor already incorportated in IEX? internet options>content advisor>approved sites and then just add the allowed websites and assign a password that she won't guess.
