As long as you are reasonably certain that your antivirus program has taken care of the infected files, for a quick fix try you can see if a repair reinstall of your version of IE helps (since Outlook Express usually arrives as part of the download - and most folks still have the download on their hard drives after they update, so the repair reinstall can be done offline in only a few minutes). In Win9x, go to Start/Programs/Accessories/System Tools/System Information . . . and from the "Tools" menu, select "Repair Internet Explorer". Or go to Start/Settings/Control Panel/Add-Remove Programs...select IE, and choose to repair.

[might want to run a doublecheck antivirus scan with an online scanner like HouseCall, just to be sure the computer is cleaned up OK
