During a Kaspersky system scan I was watching my Resource Monitor. In the Memory section it showed a constant 100 to 200 Hard Faults/sec with peaks of over 1000. The CPU utilization at that time was 15% (plus/minus). Is that many memory faults normal?

From MS Site:

--------------
Number of Hard Page Faults If a process requests a page in memory and the system cannot find it at the requested location, this constitutes a page fault. (If the page is elsewhere in memory the fault is called a soft page fault. If the page must be retrieved from disk, the fault is called a hard page fault.)

Basically, when you are doing a system scan, so much data is being loaded and unloaded from memory that the system ends up needing to pull from the page file often, which results in a hard page fault.
