First of all great product! 
Now for my question…
Is it possible to have Avast automatically delete an infected file upon finding it?
I.E While surfing I get a pop-up saying virus detected. I’d like it to just automatically delete the file without any user intervention. Is this possible? If so, could you please tell me how to set this up? Thanks in advance for your support.
anyone at all? 
You click on the icon in the tray, you see the list of providers. In your case it should be the web shield, you select “silent mode” in the options, then if I remember it well it allows you to set “yes” or “no” as default answer. Unfortunately I don’t remember what the default question is right now, but I guess you can do by yourself.
In short, the “silent mode” always answers “yes” if the question is “delete the virus?” without bothering you.
Make sure of the question then.
No, only in Professional version (see picture here: http://forum.avast.com/index.php?topic=13315.msg112285#msg112285).
In Home version you can check the option “Don’t show this window again” as soon as the first virus warning appears, and click on “No action” button. This way, nothing will be done and you will be presented the results at the end (and you can perform actions from there).
Or you can use Silent Mode:
Left click the ‘a’ blue icon.
It will start On-access protection
Click on Internet Mail and then on Customize.
Go to Advanced tab and select Silent Mode and the default answer No. This will send the file (email) to Chest.
But take a look here: http://forum.avast.com/index.php?topic=28088.msg229736#msg229736
Do the same for the and Outlook/Exchange plugin.
The answer Yes in Silent Mode keeps the virus in the file or into the message (attach) and continue the scanning. You can’t configure ‘delete the infected file’ in the Home version.
You can do the same for Standard Shield provider, but it won’t be a good idea…
Silent mode in the case of the WebShield provider simply means that avast will keep pressing the “Abort connection” button for the user automatically.
