Avast4 and Outlook

I’ve just loaded the Home edition. As the XP Home system was going to its initial restart a dialog box opened. It was only on the screen for an instant and the screen went blank going into restart. I could see an X in circle on the left side of the box. It may have been notifying of a problem with the download.
What I open Outlook, a partial Avast screen also shows over the Outlook. It appears to be the one that appears when Avast is opened. It goes away after about a second. I’ve uninstalled (Avast did not appeat in Add/Remove) using your uninstaller and reinstalled. Same problem. Any ideas?

avast! providers did not start… the X in the ‘a’ blue icon means: all providers disabled.

What do you mean? You’ve downloaded the setup file and it has errors?

The splash screen is the Outlook plugin, not the avast! (engine) splash screen.
It’s normal that it disappears.

If avast! does not appear in Control Panel, bad news: your installation is not good…
Do you use any other antivirus in your system?
Do you have any other security applications? (PrevX, startup monitor programs, etc.)?

Start up inspector for windows is installed. McAfee was uninstalled but it may not be completely gone

You should disable it to both install and uninstall avast! or, at least, allow avast setup to do its job.
Otherwise, your installation won’t be correct.

That seems the major problem… Can you find a good registry cleaner (this avast! forum has a lot of suggestions) or ask for McAfee support?
