Hello Corrente, welcome to the forums.
Unfortunately, as far as I know there is no way to determine real process behind AvastSvc.exe.
If you change avast! Web shield settings not to scan processes other than browsers, you would be able to see the real process on your firewall.
Of course, with this settings traffic from non-browser processes will not be scanned.
Settings:
Web Sheild -> Expert Settings -> Check "Scan traffic from well-known browser processes only" -> OK
Hope this helps.
P.S.
Your E-mail address is not hidden. This would cause increasing SPAMs, so I recommend to hide it.
You can change this settings from PROFILE -> Account Settings -> Uncheck "Allow users to email me".
