No problems at all… you can disable any of those providers that you don’t use. I don’t use P2P programs either. Instant messaging provider never ran on my machine. Outlook/Exchange - disable it if you don’t use MS Outlook (completely different program than Outlook Express, but of course you already know that).

If you are 100% sure your ISP checks your incoming and outgoing mails of viruses, you can disable Internet mail provider (Outlook Express) as well… why not ?

Script blocking provider is very useful if you use IE… if not, then still it can be very useful if you use Mozilla, because it works with Mozilla too. Unfortunately, Firefox is not supported, and it looks it will never be…

Cheers !
