Create QuickBooks Antivirus Exclusions: A Simple Guide for Small Businesses

QuickBooks is a cornerstone financial tool for countless small businesses, helping manage everything from payroll and invoicing to tax preparation and reporting. However, many business owners run into frustrating issues caused by antivirus software interfering with QuickBooks operations. These issues can range from performance slowdowns and connection disruptions to blocked updates and corrupted files.

To ensure your accounting software runs smoothly and securely, it's essential to configure QuickBooks Antivirus Exclusions. This article will guide you step-by-step through the process, helping you maintain both protection and performance without compromise.

Why Antivirus Software Conflicts with QuickBooks

Antivirus programs are designed to protect your system from threats, but sometimes they can be overly aggressive. QuickBooks is a large program that relies on various files, folders, and network connections to function correctly. If your antivirus software mistakenly flags any of these as suspicious, it might quarantine them or block access—leading to errors such as:

• QuickBooks won’t open or crashes unexpectedly

• Network issues in multi-user mode

• Problems installing or updating QuickBooks

• Slow file access or corrupted data

That’s why adding QuickBooks-specific exclusions to your antivirus is a smart preventative step.

What Are Antivirus Exclusions?

Antivirus exclusions are rules you create to tell your antivirus software to “ignore” specific files, folders, or processes. These rules prevent the antivirus from scanning or blocking them, reducing false positives and performance issues.

When it comes to QuickBooks, setting up these exclusions ensures your antivirus won’t interfere with critical files or disrupt communication between QuickBooks components and services.

What to Exclude for QuickBooks

Below is a list of files, folders, and services you should exclude from your antivirus scans. These paths can vary slightly depending on the version of QuickBooks and your system configuration.

1. QuickBooks Folders

Exclude these folders from real-time and scheduled scanning:

• C:\Program Files\Intuit\

• C:\Program Files (x86)\Intuit\ (for 32-bit systems)

• C:\ProgramData\Intuit\

• C:\Users\Public\Public Documents\Intuit\

• C:\Program Files\Common Files\Intuit\

2. QuickBooks Database Server Manager

If you’re using QuickBooks in multi-user mode, exclude the database server service:

• QBDBMgrN.exe

• QBCFMonitorService.exe

These are usually located in the same folder where QuickBooks is installed.

3. QuickBooks Ports

If your antivirus includes a firewall, make sure to exclude the ports used by QuickBooks:

• QuickBooks 2022 and newer: Dynamic ports are assigned during installation (example: 8019, 56728, 55378-55382)

• QuickBooks Database Server Port

• File Doctor Port: 8019

You can find your specific port numbers in QuickBooks under: File > Utilities > QuickBooks Database Server Manager

How to Add Exclusions (General Instructions)

The steps to add exclusions will vary slightly depending on the antivirus software you use (Norton, McAfee, Windows Defender, etc.), but here is a general guideline:

Step 1: Open Your Antivirus Program

Launch your antivirus software from the system tray or Start Menu.

Step 2: Navigate to the Exclusions or Exceptions Section

This is usually found under Settings, Advanced Settings, or Real-Time Protection.

Step 3: Add File and Folder Exclusions

Browse to the folders and files listed earlier and add them one by one.

Step 4: Add Process Exclusions (if supported)

Some antivirus tools allow you to exclude specific executable files like QBDBMgrN.exe.

Step 5: Save and Restart

Save your settings and restart your computer to ensure changes take effect.

Example: Exclude QuickBooks in Windows Defender

For those using the built-in Windows Defender:

1. Go to Start > Settings > Update & Security > Windows Security

2. Click on Virus & threat protection

3. Under Virus & threat protection settings, click Manage settings

4. Scroll down to Exclusions, then click Add or remove exclusions

5. Click Add an exclusion and choose Folder or Process

6. Add the relevant QuickBooks folders and executable files

7. Restart your PC

   
   

Tips for Success

• Keep QuickBooks and antivirus updated: Software updates often fix compatibility issues.

• Use trusted antivirus software: Some free or lesser-known antivirus programs are more prone to false positives.

• Document your exclusions: Keep a record of changes for troubleshooting or audits.

• Work with your IT provider: If your business has managed IT services, ask them to handle the exclusions on your behalf.

Final Thoughts

Running antivirus software is non-negotiable for cybersecurity, but you shouldn’t have to sacrifice the functionality of essential business tools like QuickBooks. By properly configuring antivirus exclusions, you can strike the right balance between protection and performance.

This simple preventive measure can save your business hours of frustration, reduce downtime, and ensure your financial data stays both accessible and secure. Whether you’re managing books solo or operating in a team environment, antivirus exclusions are a must-have part of your QuickBooks setup.
