How To Uninstall 360 Total Security Completely From Windows

Removing 360 Total Security requires a methodical approach because the software embeds deep kernel-level drivers, persistent scheduled tasks, and hidden registry keys that standard Windows uninstallation routines frequently miss. Executing a complete purge prevents leftover service conflicts, system slowdowns, and blocks lingering background processes from interfering with subsequent cybersecurity deployments.

Pre-Operation & Procedural Requirements

Successful removal of deep-system antivirus suites like 360 Total Security demands careful preparation to avoid system instability, incomplete file purges, and persistent boot-time driver errors. When security software digs its hooks into the Windows operating system architecture, standard point-and-click deletions rarely suffice.

• Essential Tools & Software: Administrative user privileges, the official 360 Total Security application interface, a dedicated third-party uninstaller (such as Revo Uninstaller or Geek Uninstaller) for deep registry sweeps, and a stable internet connection if downloading supplementary cleaner packages.
• Mandatory Prerequisite Knowledge: Familiarity with Windows Safe Mode, Windows Task Manager termination protocols, Registry Editor (regedit) navigation, and file explorer hidden item visibility settings.
• Estimated Duration & Benchmarks: The complete uninstallation, Safe Mode registry scrub, and secondary directory sweep typically require 15 to 25 minutes of focused administrative effort.

Step-by-Step 360 Total Security Removal Workflow

Step 1: Terminate Active Processes and Background Services

Before initiating the primary uninstaller package, you must kill all active threads running under 360 Total Security to prevent file-lock errors during deletion. Open the Windows Task Manager by pressing Control plus Shift plus Escape, navigate to the Processes tab, and locate any items related to 360 Total Security, 360 Safe, or QHSafe. Right-click each running process and select End Task. Next, click over to the Services tab, click Open Services at the bottom, locate services such as 360NetProtect, 360Box, or QHSvc, right-click each, select Properties, change their Startup type to Disabled, and click Stop.

Warning: Attempting to delete installation directories while background monitoring services remain active will trigger Windows access-denied errors and leave corrupted driver stubs in your kernel stack.

Step 2: Execute the Native Uninstallation Wizard

Navigate to the Windows Start Menu, type Control Panel, and open the classic control panel interface. Select Programs and Features, scroll through the list of installed applications until you locate 360 Total Security, and double-click the entry to start the native uninstallation routine. When the primary removal wizard launches, bypass the promotional pop-ups offering retention discounts or virus definitions updates. Select the option that specifies full removal, complete uninstallation, or removing all user settings and quarantined files, then click through to complete the primary phase.

Pro-Tip: If the native uninstaller fails to open due to self-protection modules, boot your computer into Safe Mode before running this step to bypass active software defense layers.

Step 3: Perform a Deep Registry Sweep for Orphaned Keys

Press the Windows Key plus R to open the Run dialog box, type regedit, and press Enter to open the Registry Editor. Navigate to the key path Computer, HKEY_LOCAL_MACHINE, SOFTWARE, and look for any remaining folders titled 360Safe, 360TotalSecurity, or Qihu. Right-click these folders and select Delete. Repeat this process within HKEY_CURRENT_USER, SOFTWARE, and check HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Services for any orphaned driver entries like 360AntiHacker or 360FsFlt.

Step 4: Purge Residual Program Data and Temp Directories

Open File Explorer, click the View tab at the top, and check the box for Hidden items to ensure system directories are visible. Navigate to C, Program Files (x86), and C, Program Files, then delete any remaining 360 folders. Next, press Windows Key plus R, type %localappdata%, and delete any directories associated with Qihu or 360 Total Security. Navigate similarly to %appdata% and %programdata% to purge remaining configuration files, log databases, and update caches.

Step 5: Execute a Clean System Reboot

Restart your computer normally to finalize the removal of kernel-level filter drivers and flush the system memory cache. Upon rebooting, open the Task Manager and Device Manager to verify that no remnants of 360 Total Security filter drivers, network monitors, or background tasks remain active on your operating system.

Comparison of 360 Total Security Removal Methods

Common Removal Failures and Field Fixes

• Root Cause: The uninstallation process freezes midway or throws an error code due to self-protection features locking core files.
  
  
  • Actionable Fix: Boot your PC into Safe Mode without networking, terminate all Qihu-related processes via Command Prompt using the taskkill command, and re-run the removal tool.
• Root Cause: Residual network filtering drivers cause loss of internet connectivity after 360 Total Security is removed.
  
  
  • Actionable Fix: Open Device Manager, expand Network Adapters, locate your active adapter properties, navigate to the Advanced or Driver tab to uninstall lingering 360 lightweight filter bindings, and reset your network stack via command prompt using netsh winsock reset.
• Root Cause: Stubborn registry keys refuse deletion, citing permission denied errors.
  
  
  • Actionable Fix: Right-click the problematic registry key in regedit, select Permissions, click Advanced, change the owner to your current administrator account, grant full control, and then delete the key.

Frequently Asked Questions

Why won't 360 Total Security let me uninstall it normally?

360 Total Security incorporates aggressive self-protection mechanisms and active defense layers designed to prevent malware from tampering with the security software. These same defensive protocols can misidentify manual uninstallation attempts as unauthorized threats, locking system files and blocking the removal wizard.

Do I need to restart my computer after uninstalling 360 Total Security?

Yes, a system reboot is strictly required to unload low-level kernel drivers and file system filters from Windows memory. Skipping the reboot can cause temporary network connection drops and prevent secondary antivirus installations from initializing properly.

How do I remove leftover files that the control panel missed?

You must manually check directories such as Program Files, Program Files (x86), AppData, LocalAppData, and ProgramData for remaining Qihu or 360 folders. Additionally, scanning the Windows Registry for orphaned keys under HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER ensures a completely clean system.

What should I do if my internet stops working after uninstallation?

Loss of internet access post-removal usually stems from lingering network filter drivers left behind in the Windows network stack. Open an elevated Command Prompt, execute a Winsock reset and IP configuration renewal, and restart your computer to restore default network connectivity.

Can I install a new antivirus immediately after removing 360 Total Security?

It is strongly recommended to wait until you have completed a full system reboot and verified that all residual files, registry keys, and filter drivers are entirely purged. Installing a new security suite over active driver conflicts can trigger blue screens of death or application crashes.

Ensure your Windows environment remains stable, secure, and optimized by verifying that all deep-system remnants are thoroughly cleared before deploying a replacement cybersecurity solution.
