360 Total Security

The 360 total security is getting worse with every single update. The company's vision for the international market is now clear. They want the international market to pay monthly for the premium version in which they will provide new features and for better cyber protection than the "Free" version. Not to mention this is covered with ads, scareware(ads), and pop up ads. While their chinese version is free fully and no ads.

Very lightweight antivirus with lots of useful tools, not junkware.
It's impact on system is barely none, you'll even forget that you have installed an antivirus.
In my experience it's better than Avira, Microsofr Security Essential, and more lightweight than Avast

It works! Cloud based + 2 optional engines (Bitdefender & Avira). Sandbox. Light on system resources. Include system cleanup and speedup utilities, if you don't want additional features, the "Essential" version is available for download. And yes, it's free.

I really like Qihoo's 360 Total Security, it's pretty good in catching vira, customizable in the ways i need, and gives me a minimum of hassle and stays silent until it's needed.

That said, the recent implementation of ads and now popup ads, really brings down the rest of the application.

And the simple fact that program updates don't have the option to happen automatically, but have to be manually checked for and initiated.

All round, i i still think it's better than most free AV software out there.

360 totalsecurity is the best for free it is way better then avast. I find avast makes my system slow on every computer I have had and i'm running the new amd - a8 cpu with a gb memory. I have tried comodo sux and as we know norton has holes in its security http://www.ghacks.net/2016/06/29/google-shames-symantec-for-security-issues/

try 360 total security for a week like I did and never looked back

They actually added a tiny amount of ads and a way to get rid of them for a monthy subscription of something like 9.99 EUR/year

HOWEVER, the functions about this AV are not affected by the payroll (at least at the time of this comment, I might update it later).

It has helped me cut down the boot time of this OS from a minute to 5 seconds and it is very clean and easy to use, I will recommend it until some major changes like how the membership will go, but it is my #1 AV.

360 Security is a free antivirus. It doesn't bothers for any license or monthly subscription. But it does not compromises with security. The firewall is amazing it immediately alarms me when any thing is happening. i would strongly recommend it rather than purchasing any other antivirus or searching for the cracks or serial key.

I have tested too many antivirus (Avast, AVG, Norton, Panda, Security Essentials, Avira, Comodo, Nod32, Kaspersky, etc) in Windows devices (Win95, 98, 2000, ME, XP, Vista, 7, 8, 8.1, 10) and this is the first time that I am proud to say that my AV really works. It's completely free and it doesn't spam you with ads or "upgrade you a account".

Also the browser's plugin is really good and is not invassive. I completely advise this AV.
