Evernote update needs Avast shutdown - Eh?

Avast Free Antivirus / Premium Security
1

I just ran an update to Evernote and it popped up a box saying that Avast antivirus needs to be stopped for the update to continue.
I refused and it continued anyway but said a reboot may be required - it didn’t ask for one in the end but I rebooted anyway.

Is this expected behaviour?

I’m running the latest AMS 9.0.2006
Evernote was updating to version 5.0.3

Fail to see how’s this an avast issue at all. Post at Evernote forums. In general, when something’s using/locking a file to be updated so that it cannot be replaced immediately, application installers produce similar kind of message.

OK, I’ll take a look at the Evernote forum, see if there’s anything there.
Just a bit of a coincidence that it never happened before and I’ve just updated AMS to 9.
