the favorites that are there can be permanently changed just by right clickng, properties, change icon.
as far as preventing the favicon from being downloaded in in the first place, I'm not sure if there'sa way to do that...the favicon is stored in the histroy portion of the temp internet files, and I don't think you want to make the that file read only.
there might be a reg hack...maybe yoyo knows.
it should be able to be done, but I don't know how.
there's a program called favorg, it's free, this program stores the favicons in a folder that you can play around with, but I'mpretty sure there's nothing in there that you'll be able to useto prevent the favicon from getting downloaded in the first place
Internet Explorer and other brpwsers have the facility whereit associates a particular icon with your website in the bookmark. It tries to obtain that icon by first requesting for "favicon.ico" from the directory of your web page.
maybe there's a way to resrict "favicon.ico
