When launching certain applications, McAfee's real-time security module may detect false positives and prevent the applications from running normally. To ensure you don't end up with misleading pop-up warnings or improperly quarantined files, add your trusted applications to the McAfee Real-Time Scanning's exclusions list. Further, if any applications have trouble connecting to online services, add those applications as exceptions to the McAfee firewall to grant them uninterrupted access to the Internet.
Excluding Trusted Applications
Open your McAfee AntiVirus Plus, Internet Security or Total Protection application, and then click the Navigation option.
Scroll down in the Navigation Center and then select Real-Time Scanning.
Select Excluded Files and then click the Add File button.
Select the executable file of the application that you want to add, and then click Open. For example, to add Mozilla Firefox as a trusted application, navigate to the Mozilla Firefox folder, located by default under the Programs Files or Programs Files (x86) folder of your Windows installation, and then select the Firefox file.
Exit the McAfee application to save the changes.
Allow Applications Through Firewall
Open the Navigation Center on your McAfee AntiVirus Plus, Internet Security or Total Protection application and then select Firewall.
Select Internet Connections for Programs and then click the Add button.
Use the Browse button to select the executable file of an application. Select Incoming and Outgoing to grant the application full access through the firewall, or select Outgoing Only to only allow outgoing traffic.
Click Save to grant the application access through the McAfee firewall. To prevent the application from connecting to risky domains, you can set McAfee's NetGuard feature to On before clicking Save.
To restore a quarantined application, go to the McAfee Navigation Center and then click "Quarantined and Trusted Items." Expand the "Quarantined Potentially Unwanted Programs" section, select the application, and then click "Restore." Add the restored application to the Real-Time Scanning's Exclusions list to prevent it from getting flagged in the future.
To exclude an application from scheduled scans, open the McAfee Navigation Center and then click "Scheduled Scans." Expand the "Excluded Files and Folders" section, click the "Add Folder" button, and then select the application's installation folder.
It you receive a pop-up warning when launching an application you trust, click "Allow" to exclude the application from future real-time and scheduled scans.
As a software developer, you can notify McAfee if your application gets flagged as malware by filling out the "Detection Dispute Submission Form" (link in Resources).
Only exclude applications that you fully trust.
