Hello @AngusNorton
Are you running Norton AntiVirus Plus?
You’re observing/reporting a known conflict.
============================================
Norton does not recommend having both Norton Security/360 and the standalone Norton Secure VPN installed on the same machine. On Windows, modern versions of the standalone VPN may explicitly block installation if Norton 360 is already present because both apps contain similar security protocols that conflict .
Why They Conflict
- Competing Drivers: Both applications attempt to manage your device’s network drivers simultaneously, which can lead to connection drops, system instability, or “strange behaviors” .
- Different Development Teams: The two products are managed by separate teams within Norton and do not communicate with each other, leading to lack of synchronization .
- Antimalware Overlap: Newer versions of the standalone VPN include malware protection similar to Norton 360, causing the system to view them as redundant or conflicting security suites .
Redundancy & Feature Differences
If you have a Norton 360 subscription (such as Deluxe or Premium), a VPN is already included as an integrated feature .
- Integrated VPN (within 360): Provides core security like a Kill Switch and Split Tunneling, alongside full antivirus and Wi-Fi security alerts .
- Standalone VPN: May offer slightly more granular controls, such as city-level server selection on some platforms, but lacks the broader security integration of the 360 suite .
Platform-Specific Behavior
- Windows: The installer often detects Norton 360 and prevents the standalone VPN from installing .
- iOS: Both can be installed, but they create separate VPN profiles. Only one can be active at a time, and switching between them often causes errors or disconnects .
If you are experiencing issues, Norton Support generally recommends uninstalling the standalone app and using the VPN feature built directly into your Norton 360 dashboard.
=============================================
Norton recommends against running the standalone Norton VPN app and the Norton 360 VPN feature on the same machine simultaneously. While they are both Norton products, they are developed by different internal teams and do not communicate with each other, which can lead to technical conflicts and system instability.
Core Recommendations
- Choose One: It is best to stick with one application. If your Norton 360 plan already includes the VPN feature, it is recommended to uninstall the standalone app to avoid redundancy and potential issues.
- Unified Interface: Using the VPN built into Norton 360 is typically preferred for all-in-one convenience and better value.
Reasons to Avoid Using Both
- Software Conflicts: Both apps attempt to manage network drivers simultaneously, which can cause routing errors, connection drops, or total loss of internet connectivity.
- Redundancy and Competition: Having both is unnecessary and causes them to compete for resources or fight for control over features like “Kill Switch”.
- Mobile Limitations: On iOS/Android, only one active VPN profile is usually allowed, leading to “duplicate profile” errors.
Key Differences to Consider
While redundant, the standalone app may offer more granular features like city-level selection, dedicated torrent support, or different privacy policy terms compared to the VPN included in Norton 360.
===============================
Norton documentation and official support community advice emphasize that you should not run both the standalone Norton VPN app and the VPN feature within Norton 360 on the same device. While they are both Norton products, they operate independently and can cause significant technical issues.
Official Stance and Documentation
- Direct Incompatibility: Norton Community users state that if you already have Norton 360, you should not install the standalone Norton Secure VPN.
- Installation Blockers: Some installation routines for the standalone VPN may even instruct you to uninstall Norton 360 first to prevent conflicts between the two products’ security features.
- Redundancy: The “Secure VPN” feature in Norton 360 is designed to provide the same core protection as the standalone version. Installing both is unnecessary and consumes extra system resources.
Known Issues if Both Are Present
If both are installed, you may experience:
- Connection Drops: Both applications may fight for control over your device’s network drivers, leading to frequent disconnects.
- Profile Conflicts (Mobile): On iOS, each app installs a separate VPN profile. Only one can be active at a time, and running both can lead to “duplicate profile” errors.
- Troubleshooting Difficulty: Because the two apps do not communicate with each other, it becomes difficult to identify which one is causing a network or security error.
Recommendations
- Stick to Norton 360: If your plan includes the VPN, it is recommended to use the integrated version and uninstall the standalone app for better stability.
- Protocol Differences: Use the standalone app only if you require specific advanced features—like city-level server selection or specialized “Double VPN” servers—that might not be present in your current 360 version.
==============================================
The conflict is similar with Norton AntiVirus Plus, but the circumstances differ because this plan is the only major Norton offering that does not include a built-in VPN .
If you attempt to install both on a Windows machine:
- Potential for Blocked Installation: The latest versions of the Norton Secure VPN standalone app are designed to check for existing Norton software. In some cases, the installer may still block the process even if the existing product lacks VPN features, simply because they share underlying network management drivers .
- Feature Overlap (New Tiers): Modern versions of the standalone VPN (specifically the Plus and Ultimate tiers) now include their own malware protection, AI scam detection, and password managers . Installing these alongside AntiVirus Plus creates a direct conflict between two different real-time antivirus engines, which can cause system slowdowns or software crashes .
Should you use both?
Generally, no. If you need both antivirus and VPN protection, Norton’s official recommendation is to upgrade to a Norton 360 plan (Standard, Deluxe, or Premium) .
Practical Workaround
If you already own separate subscriptions and want to keep them:
- Check your VPN tier: If you have the basic “Standard” standalone VPN (without malware protection), it may run more smoothly with AntiVirus Plus than the “Plus/Ultimate” VPN tiers .
- Contact Support: If the installer blocks you, you can contact Norton Support to see if they can merge your remaining subscription time into a single Norton 360 plan, which is often more cost-effective and avoids all technical conflicts.
