Here is a website with a hundred infected sites’ addresses.
Well a hundred infected sites is a drop in the ocean. The network shields malicious sites list I suspect has many more than just one hundred as it has a massive user base providing information via the avast ComunityIQ function (web shield detections being just one resource used).
This is one of the largest databases of malicious sites, http://www.malwaredomainlist.com/mdl.php.
Also see http://www.avast.com/en-gb/community (facts tab) and see the number of infected domains and it will make you think 100 is a pity full number.
http://www.avast.com/maps
and click on infected websites by country
then select country and there you go - 10 last infected domains per country…
Nice feature from avast!
Looks like he needs a lot of help: 
HELP! My desktop computer has gone WACKO with avast and internet defender!
