I'd like to see something related to ads, and concur that ads might not be security-related.
At the very least, let me know when an application I am installing or just installed will push ads.
Blocking ads totally is likely impractical - after all we do get a bunch of apps free and ads support it, though I much prefer to donate to the author if the app is worth it and at least a dozen or so are worth having.
I don't need links to removal or any other fancy features, as that can be easily done through the Setup menu.
I liked it, and posted about it, when DrWeb warned about some audio-video app full of AirPush ads.
