360 Security?
Colleague is using it and looks nice. Scans the phone to free up memory from temps files, and the usual virus scanning.
You don't need crapware like this on your phone. It's a waste of resources and only drains your battery.
What Virus is your phone going to get? Nothing. Exactly. Your memory card may pick up something if you stick your phone into unknown systems, but that's about as far as it goes.
Phones do not get viruses/malware. Your Temp files is managed by Android too, so leave it alone. You don't need to delete it every day, because you think it makes it faster. The inverse happens, you are deleting much needed cached content and slowing down your experience on your device, again, wasting processing power and draining your battery.
