Guest "me" - I was concerned about the effects of having two browsers on my Windows-entrenched puter too, but finally downloaded Firefox (which is free, from mozilla.org) and their email programme Thunderbird (ditto). There have been no problems whatever - I simply don't open IE anymore, though it's still functional. So there IS an alternative to The Geek, and if I need to use IE for any reason (haven't found one yet) it's just a matter of clicking on it. Firefox's security options are easy to get at, and the first thing I did was turn off Javascript and block popups. Give it a try, because you can always uninstall. It's not like having two operating systems.
