Prevent malicious apps from running in the background with Drowser. Browser is a simple application that kills selected applications when the screen turns off. It requires root and uses it to kill apps with a 'force stop app-id'. This is a very impolite way to stop apps. These could (and probably will) misbehave. You can also lose data due to this. Beware!
