There is no particular internet security that has 100% detection capability, but I have personally tried all those that you mentioned, and I can tell you categorically from experience that 360 total security 7.6 2016 released on Sept 28 2015 is better than all those and it gives you greater peace of mind. 360 total security 2016 already has multiple engine protection consisting of avira, Bitdefender, QVMll, System repair engine, 360 cloud scan, identity protection, anti hijacking protection, and many more. All you need do is to activate and update them once you install 360.The package subsequently continues to update automatically. The developers of 360 keeps improving it everyday and new features are being added regularly, so you can only imagine what more you stand to benefit from 360 as time goes on.
