I'm not sure if that would be considered abnormal, but maybe some of my colleagues can contribute here.
It's virtual memory that's being used if and when the application is active.
Mine is shown in the attached picture, click it to magnify if needed.
I should point out though that on Windows 8 I'm using McAfee Beta software, MSC v12.9, but it shouldn't behave all that differently.
If you are really concerned about it, contact Technical Support. It's free by phone or online chat and linked under Useful Links at the top of this page.
Thanks for your reply.
Well, I just think this is a very high consumption.
Right now I'm using a PC with Windows 7 which has another antivirus and none of the Windows's processes is consuming more than 190KB of memory. The antivirus consumes about 18KB, so I thought to be strange McAfee's memory consumption.

It's not actually consuming it, rather it's reserving virtual memory. It's the CPU cycles that are being used when it's scanning something, or updating, that matter for performance issues.
Technical Support would be able to explain it better than I can however.
