McAfee Antivirus software provides you with protection from viruses on your computer. Some people run key generation, or keygen, programs to create serial numbers for their software. These keygen applications get picked up by McAfee, and the software automatically identifies them as a virus and deletes the program. To stop McAfee from deleting software or flagging it as a virus, you must set up an exception in the main configuration window.
Double-click the "Security Center" icon in the main Windows system tray. This icon opens the main configuration window for McAfee.
Click the "Internet Applications" tab on the left side of the window. In this configuration section, click "New Allowed Application." This button opens a new window where you specify your keygen software as an exception.
Click the "Browse" button in the "Select Application to Allow" window. Double-click the keygen's EXE file name, and click "Next." Check the option labeled "Allow Full Access" in the "Permissions" window. Click "Close" to save the changes.
Close the keygen application before setting up its permissions in the Security Center.
