So, my computer recently got a virus attack and i factory reset my windows 10 because i'm afraid it'll pop out again.

but after the reset is done, i realize that it consumes 6% more RAM during idle.
before the factory reset, it's always at 14 - 17 (around 1.5gigs), now it's 22 - 29 (around 2 gigs).

i've been shutting down as many background services and apps as it could.
but it stays that way.
i tried scanning it for viruses but it detects none.

it's been almost a week and this issue hasn't been resolved.
is there a way i could get it back to normal?

fyi: My total RAM is 8078 mb (7890 usable)
