The internet mail scanner will not scan the emails, because you are using
a) secured email (gmail)
b) a browser to view them.
You will need to use something like thunderbird (and stunnel for the gmail - not sure about yahoo)
However,
In the time since I have used avast!, I have only been infected once (not my fault
![Wink ;)](https://forum.avast.com/Smileys/default/wink.gif)
) If it weren't for the mail scanner, I wouldn't have known (it alerted to loads of emails being sent...)
I choose to have all of the previders running, purely because of this experience, however you can choose to disable it if you want.
I think these are right:
ashDisp.exe = tray icon/GUI
ashMaiSv.exe = Mail scanner
ashServ.exe =Actual scanning engine
ashWebSv.exe = Web Shield
aswUpdSv.exe = update service
