XP Pro S/P3 / MS Office 2010 / Avast Pro

[PBS]

I recently upgraded to office 2010.  after the installation was complete, my e-mail did not work.  Neither Outlook 2010 or Outlook Express.

The only way I could get my e-mail to work was to disable Avast.  I suspect some clash somewhere.

I also have a machine with Windows 7 Pro / MS Office 2010 / Avast Pro, without any of the above problems.

Any ideas?

I suggest an avast installation from scratch. Maybe it could address the issues.
Which is your firewall?

1. Download the latest version of avast! Uninstall Utility and save it.
2. Download the latest avast! version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can't run it, try booting in Safe Mode and doing it from there. Anyway, boot after you've run it.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro.
7. Check and post the results.
