Administrators are expected to tune each instance of the real-time antimalware scanner to the needs of the specific environment. So, a real-time antimalware scanner is expected to compound existing CPU utilization, but isn’t the driving force behind system resource consumption.īecause McAfee Enterprise software exists in a diverse range of environments, it’s impossible to provide a default configuration that meets the needed balance between protection and performance in all possible environments. If the system is idle, the scanner is idle. The real-time antimalware scanner CPU use is proportional to the amount of disk activity that occurs on the system. If the file is malicious, an action is taken on it. If the file isn’t malicious, it’s returned to the process that requested it. The scan engine then returns a decision about whether the file is malicious. This component intercepts the file and delivers it to the scan engine. All McAfee real-time antimalware scanners operate by inserting a component that is used to monitor all disk access requests made by any process running in memory.
