Don't know why you posted a question as an Anonymous Coward, but... .
1) Comcast's filters notice you're infected; for example they see your machine send 200,000 emails in a day.
2) You request a webpage.
3) Regardless of the webpage, they can intercept the HTML on its way to your browser and insert something like (don't know how much code Slashdot will let me post but here goes)
(wait for HTML tag and body tag)
document.writeln('');
(send the rest of the page)
With that inserted, your browser will now call out to Comcast's servers and load that
var div = document.createElement('div');
div.innerHTML = "You've got a virus! You've sent 200,000 emails a day non-stop for a week - or at least your infected machine has without your knowing. To fix it take the following instructions
div.style = 'position:absolute;left:50%;top:50%;margin:-100px 0 0 -200px;width:400px;top:200px;background:#fff;border:3px solid #00f;z-index:1000';
document.body.appendChild(div);
That puts a nice large box up in the middle of the page with that message. What's going to be really difficult is making it clear this is real, and doing it in a less-obtrusive way - for example stuffing it up at the top of the page and giving you an easy way to make it go away.
I think email and free antivirus software are better ways of notifying you (make a deal with McAfee to be able to send your own antivirus alerts via their software)
