It can't be uninstalled cleanly
The biggest problem with 360 is not that the uninstall process is complicated, but that it cannot be uninstalled cleanly. It attaches part of its core to the core of the Windows system like a virus. This part cannot be uninstalled, even after uninstalling the main part. After a period of time, the remaining core will secretly automatically download the 360 main program and install it secretly. Even because this core is intentionally spread to different partitions and locations on the hard disk, reinstalling the system may not be able to clear it out. There has never been a 100% clean method other than completely formatting the hard drive.

Hi, We are very sorry to hear about your frustrating experience. Because 360 is a security software, its core components must integrate deeply into the Windows system to effectively protect against threats. However, it should absolutely never reinstall itself secretly, and it can be completely removed without formatting your hard drive. We want to help you get this fully resolved. Please contact our technical team at [email protected]. We can provide you with the correct procedures and official tools to ensure every component is completely and safely removed from your system.
