If your computer seems slower after installing Norton, try these optimization steps:

1. Ensure you have the latest version of Norton installed by checking for updates
2. Adjust your scan schedule to run during times when you're not actively using your computer
3. Use the Norton Power Eraser tool to check for resource-intensive applications
4. Configure Norton's silent mode to reduce notifications and background activity
5. Run Norton's Optimize feature to clean up temporary files and free up system resources

You can also try Norton's Performance Optimization tools to improve your system speed.

Long scan times can be caused by multiple factors:

• The number of files on your computer (more files = longer scan time)
• Your computer's specifications (CPU speed, RAM, etc.)
• The type of scan being performed (Quick Scan vs. Full System Scan)

To improve scan performance:

1. Use Quick Scans for routine checks and limit Full System Scans to weekly or monthly schedules
2. Configure Norton to exclude trusted folders that contain large files or many files (like media libraries)
3. Close other applications while scanning to free up system resources
4. Make sure your Norton product is up to date

If you're having trouble accessing your Norton account, try these steps:

1. Verify you're using the correct email address associated with your Norton account
2. Reset your password using the "Forgot password" link on the login page
3. Check your email spam/junk folder for password reset messages
4. Clear your browser cookies and cache, then try logging in again
5. Try using a different web browser or device

If you still can't access your account, you may need to contact Norton support to verify your identity and restore access.

If you've renewed your subscription but Norton still shows as expired, follow these steps:

1. Sign in to your Norton account to verify your renewal was processed successfully
2. Check that the renewal was applied to the correct subscription
3. Ensure the device you're using is connected to the internet
4. Open Norton and manually check for updates through LiveUpdate
5. Try signing out of your Norton account in the product and signing back in

If the issue persists, check your payment method to ensure the renewal transaction was completed successfully.

Error codes 8504 and 104 typically occur during installation when there are conflicts with other security software or corrupted Norton files.

To resolve these errors:

1. Uninstall any other antivirus or security software from your computer
2. Download and run the Norton Remove and Reinstall tool
3. Restart your computer after the removal process
4. Disable Windows Defender temporarily during installation (for Windows 10/11)
5. Download a fresh copy of the Norton installer and run it again

These errors indicate that critical Norton services have stopped or are experiencing issues.

To fix these problems:

1. Restart your computer to reset all services
2. Check for Norton product updates through LiveUpdate
3. Run a Quick Scan to check for malware that might be interfering with Norton
4. Use the Norton Autofix tool to repair service issues
5. If problems persist, try uninstalling and reinstalling Norton using the Remove and Reinstall tool

Important: Tamper Protection errors should be addressed immediately as they may indicate a security breach attempt.
