Yes, sometimes we get ‘tired’… sorry for the non informative post…
Anyway, RejZor said everything you asked (about the priority, it’s ok for HIGH, and about the Task Manager, use the Virtual Memory column). David said correctly that, most often, two values are very different one from another.

Can you see if you use the ‘Custom’ level of protection in Standard Shield (un-checking the scanning of open/created/modified files) it helps?
