360 Total Security is an all-in-one security and optimization suite that allows you to protect your PC while simultaneously improving its overall performance. Unlike traditional antivirus software that only looks for malware, this software offers advanced disk cleaning, system acceleration, and boot management tools within a very visual and intuitive interface. Here, the focus is on offering comprehensive maintenance so that you don't have to install a multitude of independent programs when it comes to looking after your computer's health.

Multi-engine power for a comprehensive defense

If there's one thing that makes 360 Total Security stand out, it is its protection system. This advanced model combines multiple analysis engines in parallel, including AI-based technologies like QVM II and the 360 Cloud Scan Engine. When you start the scan, the program doesn't just look for traditional viruses such as Trojans or ransomware, it also monitors your system's behavior in real time. This means that, if a suspicious file attempts to modify critical logs or encrypt your data, the tool will block it before it causes irreparable damage.

Optimization and cleaning in one click

In addition to its security features, 360 Total Security is also adept at restoring fluidity to your computer. With its dedicated tools, you can remove countless GB of junk files, hidden caches, and remnants of poorly uninstalled programs slowing down the hard drive. On top of that, the startup manager graphically analyzes which apps launch with the operating system so you can disable the processes you deem unnecessary. This allows your Windows computer to start processes in half the time and respond more smoothly on a day-to-day basis.

My experience with 360 Total Security

When I installed 360 Total Security on my Windows 11 PC, I liked the simplicity of the interface clearly divided into side tabs. I decided to put the "Full Check" feature to the test, and the software performed a fairly quick simultaneous scan, detecting not only ways to improve performance but also several high- and medium-risk threats camouflaged in browser extensions and system files. During the disinfection and repair process, I was able to check the path of each generic Trojan in detail before removing it. After completing the log cleanup and freeing up more than 4 GB of junk files, the "Boot Time Analysis" menu showed me, with the help of a very intuitive graph, how my computer's boot time decreased significantly compared to previous days.

What I liked most about 360 Total Security and what could be improved

What I liked most: Having the powerful antivirus and system optimizer unified in the same menu is highly convenient. The visual breakdown of the detected threats gives you complete control over what you are deleting. What's more, the boot time graph is very helpful for understanding PC performance improvements.

What could be improved: The notifications to get you to upgrade to the premium version can detract from the user experience at times.

Download 360 Total Security for PC and keep your operating system free from digital threats while you regain boot speed. Browse with confidence, clean the hard drive with a single click, and monitor your computer's health in the simplest and most effective way possible.

You shouldn't use the app because it has the virus W32.Malware.Gen and Win32/Qihoo360.M, potentially unwanted application.

It's good, but it's a pity that it's not premium.
