I think the idea of detection of
phishing and malware sites which FF uses (i think borrowed from google/stopbadware) being in Kaspersky would be good seeing as its blacklists seem to work so much better than kasperskys and protect from many driveby and fraudtool websites, obviously for those who use other web-browsers.
The viruslab can maybe also add to the blacklist IP addresses which malicious downloaders connect to seeing as those servers are likely to host many other malicious files which other downloaders connect to.
If the above functionality is already there (I think the potential is there), maybe KL should use it.
