Why doesn't the warning box have any clickable links so that we can investigate the threat found?
Also is there any way to turn off the voice message that it's updated 3-4 times a day?

As for the topic, and the related ad site,
It is listed in HpHosts: http://hosts-file.net/?s=uac.advertising.com <-- Engaged in Phishing, interestingly, added in 2009 (24-01-2009)
Not sure what to make of that really...
