360 Total Security is one of the most complete and effective free antivirus programs available, and will protect you from the majority of threats you might face online.
Virus protection and more
The antivirus uses five antivirus engines, including 360 Cloud Engine, CVMII, Avira, and Bitdefender. Scanning your PC for threats is quick, and we were impressed by its attention to detail. For example, if removing a detected threat requires a PC restart, 360 Total Security will tell you.
The Avira and Bitdefender engines are disabled by default. This is good, as enabling them increases RAM usage, but you have them as an option if you want to be extra secure. 360 Total Security also includes an optional browser extension which will notify you if any pages you visit are potentially malicious. This seems like overkill to us, as most browsers today will warn you if a site is not secure or dangerous.
Use with care
The Speed Up and Clean Up features are mixed blessings. Both work, but are not as user friendly as they could be. You may find with Clean Up that it suggests deleting files that cannot be deleted as they are in use, which is annoying.
Speed Up does indeed free up RAM allowing you more power to run games and resource hungry apps. but we did have some problems. We had to reinstall Google Chrome after running Speed Up, as it had made changes without warning us, meaning Chrome no longer worked.
Easy to use and not intrusive
360 Total Security is really easy to use, with a clear interface that's simple to navigate. It explains what every feature does, and it's easy to configure. If you're looking for an antivirus solution that's not intrusive and lets you get on with whatever you're doing, 360 Total Security is a good choice.
