One of the better freeware antivirus program is Gladitor, it will scan most everything going in and out of your system including linked with outlook and outlook express

The interface on outlook is pretty much the same as express, but outlook is much more powerful as far as the email filters go, as weel as a handful of other great tools to keep track of your day and life. I use the calendar and the task list all the time to make sure i got everything upto date. If you have an office xp cd i would just install it. I could never get used to any other email client, including endura and a handful of others.
