Unfortunately the latest addition won't allow for the inclusion of an undetected malicious site (without a file), I tried a test and that failed.
So you would have to create a notepad file with the URL inside as a work around, if you are going to have to do this, you might just as well send an email.
So it still doesn't cater for reporting Undetected malicious/phishing sites only reporting FPs on sites. Essentially it is using the old methods, sending an email to virus (at) avast (dot) com (no attachment as there is no physical file) outlining the issue and giving the URL in the body of the email.
The email Subject is probably more crucial as I would say it still has to be called 'Undetected Malware' for it to be filtered within the receipt system for action. I would go further and include 'Network Shield' in the subject to further define the problem and possibly attract attention. So the subject would be something like "Undetected Malware - Network Shield - Phishing/Malicious site" (whichever is applicable), without the Quotes.
