High memory usage - VadL?

[Windows Central Question]

I appear to have a memory issue.
Unfortunately not sure when it started, and I have since installed Build 10532.

Anyway, system has 16Gb RAM and even on fresh boot is running at 70% utilised with 8.5Gb in the Non Paged Pool alone.

It was fine under Windows 8.1 - which was then upgraded to Windows 10 Build 10240 initially.
I have run Poolmon to see what is happening, the top non paged item is VadL (virtual address descriptor - long) which seems to be related to virtual memory, but not sure why this would suddenly use a lot of physical memory.

I've looked at two other Windows 10 Build 10532 machines and neither have this issue (with 4Gb and 8Gb installed).
Anyone got any ideas?

The same issue. Windows 10 10532. 8.5 gb used by VadL

Same issue!
Apparently its caused by Kaspersky Internet Security. This memory leak on VadL started after installing it. I've checked some links and more people have the same problem.:unhappysweat:
