The “Learn More” links for the 3 avast! products on this page:
http://www.avast.com/en-ca/index#tab2
are screwed. They used to work fine, now they give a 404 error.
The reason appears to be that the URLs in the links have been changed from:
en-ca (English: Canada)
to
an-ca (non-existent).
http://www.avast.com/an-ca/free-antivirus-download
http://www.avast.com/an-ca/pro-antivirus
http://www.avast.com/an-ca/internet-security
Manually changing the URLs to en-ca takes one to the correct pages as previously.
