I didn't deny that. It exists, but it doesn't just magically appear on your device. You have to choose to install the malware yourself. What evidence do you have of that? Can you point me to a single news story on Android malware that doesn't involve users installing the malware? (Carrier IQ doesn't count, because antivirus wouldn't do anything about it anyway, it comes with the phone, and you can't really uninstall it without rooting.) No, I don't. Antivirus doesn't really do anything useful. Instead, I use real security practices (e.g., installing system updates regularly, using NoScript, using common sense, making regular backups). And antivirus still never knows. I don't know why people think antivirus companies have some secret all-knowing database that can proactively telepathically know about malware before it hits. It's useless. And I am, as a matter of fact, opposed to background processes that are unnecessary.
