McAfee Online Virus Scan - MCAGENT
MCAGENT.EXE belongs to McAfee’s Online Virus Scan. When you install McAfee’s Online virus scanner, an icon with a red "M" is placed in your system tray. This notifies you that your Online virus scanner is active. It can be used to set scanning options or to access reports on recent scans. It can be removed but we’d recommend leaving it alone if you use McAfee’s online scan.
