Weird string exe file in AVAST directory wants to access the internet

Hello!

Today my firewall notified me that the following file wants to access the internet:

C:\program files\avast_antivirus\setup\b6c524fd-5eb0-44b3-b9a2-75f8683d4530.exe

What is this? I have installed Avast 8 (on W7) some weeks ago.

It’s an avast! Emergency Update. Allow it.
