"Infection Blocked" Message - for Avast Iteself

Hello. Got a “Infection Blocked” message when Avast attempted update.

Infection details show emupdate.avast.com . . .

What OS/SP ?
What exact version of avast ?
At what point do you get the message ? (when booting, when manually updating or…)

Thanks, Eddy

Here are answers to your questions:

Windows 7
Avast 10.4.2333
On boot

You need to install the latest version of avast
