Have you been downloading apps from the internet ?

I used Lookout for a bit too, I found Zoner to be so much more powerful with it's anti malware support and overall protection.

As for my battery it holds fairly well untill it reaches 15% then it drops rapidly but I doubt it's app related just the battery itself.

On another note if you've had the battery for awhile or even if it's potentially faulty you could look at getting another one. S2 batteries are fairly cheap.

I believe it's called air push advertising.
It will have come a part of an app or theme that you have recently downloaded.
There is an app for blocking them, I think it might be called air push, but my preference is to just uninstall the app.
