ashOutXt.dll loading error

how do I fix the error
the add in c:\programfiles\AlwilSoftware\Avast4virus\ashOutXt.dll
could not be installed or loaded. This appears when I start Microsoft Outlook. Could someone please help…Thanks

What version of Outlook are you using? And operating system?

Is the path to the file correct? I mean, does the file at the given path really exist on your machine?

Thanks
