What Is an Antivirus Exclusion?
An exclusion tells your antivirus software to ignore certain folders or programs when scanning. When you exclude QuickBooks files, you reduce the chance of the software mistakenly blocking or deleting important data.
How to Create QuickBooks Antivirus Exclusion
The process varies slightly depending on which antivirus software you're using (Norton, McAfee, Avast, Windows Defender, etc.), but the QuickBooks folders to exclude are the same.
Step 1: Identify QuickBooks Files and Folders to Exclude
Here are the essential paths you should always exclude:
For QuickBooks Desktop (Default Install Paths):
Also exclude these executable files:
-
QBW32.exe – QuickBooks main executable
-
QBDBMgrN.exe – Database Server Manager
-
QBCFMonitorService.exe – Company File Monitor
-
IntuitSyncManager.exe – Sync Manager
-
QBLaunch.exe – Startup launcher
-
AutoBackupExe.exe – Automatic backup tool
Make sure to replace [YourUsername]
with your actual Windows username when entering paths.
Step 2: Create the Exclusion in Windows Defender (Example)
If you use Windows Security (built into Windows 10/11):
-
Open Windows Security from the Start menu
-
Go to Virus & threat protection
-
Click Manage settings under Virus & threat protection settings
-
Scroll down to Exclusions, click Add or remove exclusions
-
Click Add an exclusion, then choose Folder
-
Browse and select each QuickBooks folder listed in Step 1
-
Repeat for each file or folder needed
Step 3: Create the Exclusion in Other Antivirus Software
For Norton:
-
Open Norton Security
-
Go to Settings > Antivirus > Scans and Risks
-
Under Items to Exclude from Scans, click Configure
-
Add the QuickBooks folders and files
For McAfee:
-
Open McAfee
-
Go to Real-Time Scanning > Excluded Files
-
Add QuickBooks program files and folders
For Avast:
-
Open Avast
-
Go to Menu > Settings > General > Exceptions
-
Add each QuickBooks path and executable file
🔒 Tip: Always consult your antivirus documentation for the exact steps.
Step 4: Restart Your Computer
After exclusions are added, restart your PC to ensure the antivirus applies the new settings.
Once rebooted, open QuickBooks and check for improved performance.
Step 5: Update QuickBooks and Antivirus Software
Outdated software can still conflict even with exclusions. Make sure:
-
Your QuickBooks is updated to the latest release
-
Your antivirus software is up-to-date
-
Windows is running the latest updates
This ensures compatibility between your tools.
