1. Open the security guard (I went to official website to download 360 security guards) and enter the home page of security guards. At the top of the page, we can see the "complete collection of functions".
2. Click on "Function Daquan" to enter all the function pages of Security Guard, where you can find "System Disk Slimming" (I directly search for "System Disk Slimming").
3. Click "System Disk Slimming" to open the System Disk Slimming page. At the bottom of the page, we can see "file move" and "restore" at the file move location. Right-click the 360movedata folder to pop up the right-click drop-down submenu, find "Delete" in the submenu, and click "Delete" to delete the 360movedata folder.
