I have been using 360 security for a long time and wanted to share my views about it.
This is a very good app for those who want a cleaner, ram booster, antivirus, app locker all in one pack.
It does all these things very effectively and thats why I am still using it. It has a good antivirus engine that scans apps and also has full sd card scan option and does very good detecting any virus to android.
It comes with a junk file cleaner which notifies when to clean junk files and other unnecessary files that are occupying space in ur phone.
The ram booter helps in cleaning ram when phone feels slow with a very cool animation. It also has an app locker built in which can lock selected apps with a pattern or password which used by a lot of user.
One more thing is the calls and sms filter which is a very handy feature. It also notifies which apps are starting in the background every time we start the phone and also cools down and repair battery life. All these feature makes this app a must have for any android device.
