Excessive Memory Usage after scanning "Operating Memory"

[adam_72]

Folks,

concerning avast free 5.0.418 on windows 7 x64:
memory usage increases by factor 1,5 (or even doubles) while performing a custom scan "Operating memory of the Computer", high usage remains even after scan completed  !

Anyone else experiencing this ?

Other than that no glitches so far, looks pretty mature for a major product upgrade !

Thanks

It's normal.
When scanning the memory, all the memory of all running processes has to be "touched" - which means the operating system has to load all memory pages that we not loaded before (because they were not needed, for example), so the value of "memory usage" increases (might be even much more than 2 times).

Sure, it stays even after the scan is completed - it's up to the operating system to decide that a particular page is not needed, and "forget it" (or swap out) again.
