I have an automatic preview i always thought was not a good idea, basically that will mean u have opened it and if u get a bad email then u could be in trouble, especially if the email is from an uknown sorce. As for Hotmail, that has notrons or McAfee to scan all there emails & for anything you download from ur Hotmail account, then if Kaspersky is any good then i will check that as you download it. You can if you wish use Windows Mail to download all ur emails from ur Hotmail account.
I'm not a Vista lover, but i believe this is what you need if thats what u wish to do. >>click here
Best of luck !!
