Okay I looked it up

InMem KB
Amount of physical memory (in kilobytes) used by the process.

Private KB
Amount of Virtual Memory used privately by the process. It usually corresponds to heap allocations.

Total KB
Total amount of virtual memory (in kilobytes) used by the process.

Okay, based on these finding above Avast Service and Email Scanner combined is 11,256KB of RAM (Not virtual memory). The PrivateKB and TotalKB refer to virtual memory.

So, my questions are what is the deal with Windows TaskManager? Is it showing a combination of RAM and Virtual Memory as one total? Could this be what is confusing a lot of new users concerned about the memory usage?
