question, how to deal with found viruses?

[brockey01]

do scan results lets you take care of found viruses?
 
also is there a way to set Avast to automaticly delete virus when you try to download files that are infected?

Select Silent Mode for Web Shield and Standard Shield. Malicious files will be moved to Chest (Quarantine) automatically. Not exactly delete but very close plus you can restore the files in case of false positive.

Only in the Professional version.

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.

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 hte user automatically.
